    Abstract: 1,202,498. Silyl isocyanurates; polysiloxane adhesive compositions. GENERAL ELECTRIC CO. 19 Aug., 1968 [20 Sept., 1967], No. 39645/68. Headings C3S and C3T. The invention comprises silyl isocyanurates of the formula wherein R is a C 1 _ 8 alkyl radical, R 1 is a monovalent saturated hydrocarbon or halohydrocarbon radical, R 11 is a divalent saturated hydrocarbon or halohydrocarbon radical, G is a radical R 1 or (RO) 3-a R 1 a SiR 11 - or a monovalent unsaturated hydrocarbon or halohydrocarbon radical and a is 0, 1, 2 or 3. They may be prepared by reaction of appropriate amounts of the hydrosilane (RO) 3-a R 1 a SiH with the corresponding unsaturated isocyanurate i.p.o. a Pt catalyst; the trisilyl isocyanurate may be obtained also by reaction of the silylorganohalide with a metal cyanate in an aprotic solvent. In Examples 1-3 trimethoxysilane is reacted with triallyl isocyanurate in molar ratios of 1, 2 and 3: 1 to give the corresponding mono-, di- and tri-silyl isocyanurates. In Example 4 phenyldiethoxysilane is reacted with allyl dipropyl isocyanurate. Two parts by weight of the tris(trimethoxysilylpropyl)isocyanurate of Example 3 are mixed with 100 of a hydroxy-terminated polydimethylsiloxane, 150 of a silica filler and 0À8 of a curing catalyst to give a room temperature vulcanizing (RTV) composition used to bond plywood strips.

    Abstract: Organopolysiloxanes comprise units and optionally where R is a hydrocarbon, halohydrocarbon, cyanoalkyl or fluoroalkyl group, Z is an organo-metallocene radical -R1-[C5W4]M[C5Q5], where R1 is a divalent hydrocarbon radical or -R11-Y-, where R11 is a divalent hydrocarbon group of at least 2 C atoms and Y is a carbonyl, carbinol, carbamino or carbazido group, M is a transition metal, Q is H or an electron donating or electron withdrawing radical e.g. aryl, hydroxyaryl and hydroxy-, cyclo- and nitro-alkyl; or acyl, haloalkyl, sulpho, and carboxy-, nitro- and haloaryl, a is 0, 1 or 2, and b is 0, 1, 2 or 3. The transition metals are those of atomic number 22-28, 40-46 and 72-78, Fe, Ru and Os being preferred. The products have an average formula , wherein f is 0 to 2.5, g is 0.001 to 1 and f + g is not greater than 3. The polysiloxanes may be prepared by the hydrolysis of the corresponding halosilanes ZSiRaX3- a and RbSiX4- b, or the disiloxane ZSiR2\OSiR2\Z may be prepared by dealkylation and hydrolysis of an alkyl metallocenyl silane. Examples describe the preparations of (CH3)3SiCH2CH2CO (C5H4)Fe(C5H5) and the corresponding osmocene compound from the metallocenes and (CH3)3SiCH2CH2COCl in the presence of AlCl3, the reduction of (CH3)3SiCH2CH2CO(C5H4)Fe (C5\H5) to and the preparations of disiloxanes from these compounds by treating them with concentrated H2SO4 followed by hydrolysis. In other examples and are hydrolyzed alone, and the former also with (CH3)2SiCl2, to give polysiloxanes.

    Abstract: Lubricating compositions comprise bis (silylmetallocene) compounds of the formula [(R1)3Si-R-Y-Z-Y1]2A, where R is a divalent hydrocarbon or halohydrocarbon radical having at least 2 carbon atoms, A is R or methylene, R1 is a monovalent hydrocarbon, halohydrocarbon, cyanoalkyl, fluoralkyl or halogen radical, Y and Y1 are carbonyl, carbinol, carbamino, carbazido or methylene, Z is a divalent metallocene radical -[Q4C5]M[C5Q4]-, where M is a transition metal, Q is hydrogen, aryl, hydroxyaryl, cycloaliphatic, nitroaliphatic, aliphatic acyl, arylacyl, carboxyaryl, aldehydic, sulpho, carboxyaryl, nitroaryl, haloaryl or haloaliphatic.ALSO:The invention comprises bis-(silylmetallocene) compounds of the formula [(R1)3Si-R-Y-Z-Y1]2A where R is a divalent hydrocarbon or halohydrocarbon radical having at least 2 carbon atoms, A is R or methylene, R1 is a monovalent hydrocarbon, halohydrocarbon, cyanoalkyl, fluoralkyl or halogen radical, Y and Y1 are carbonyl, carbinol, carbamino, carbazido or methylene, Z is a divalent metallocene radical -[Q4C5]M[C5Q4]-where M is a transition metal, Q is hydrogen, aryl, hydroxyaryl, cycloaliphatic, nitroaliphatic, aliphatic acyl, arylacyl, carboxyaryl, aldehydic, sulpho, carboxyaryl, nitroaryl, haloaryl or haloaliphatic. Specified metals are titanium, vanadium, chromium, manganese, iron, cobalt, nickel, zirconium, columbium, molybdenum, technitium, ruthenium, rhodium, palladium, hafnium, tantalum, tungsten, rhenium, osmium, indium and platinum. The compounds may be prepared by (1) reacting a dibasic acid anhydride XCOACOX, wherein X is halogen with two moles of the silylorganometallocene at - 25 DEG to 100 DEG C.; or (2) acylating a metallocene [Q5C5]M[C5Q5] with XCO.A.COX and acylating the product with two moles of a silylcarboxylic acid halide (R1)3Si-R1-COX; the carbonyl groups may be converted to other Y and Y1 groups by conventional methods. Suitable dibasic acid halides are o-, p- and m-phthaloylchloride, malonyl chloride, adipylchloride, succinylchloride, glutarylchloride, sebacoyl chloride; oxalylchloride yields bis-(silylmetallocene) compounds free of A radicals. Compounds containing a hydrolysable group may be hydrolysed to polysiloxane polymers and copolymers containing metallocene units. The examples describe the preparation of (1) 11,11 - bis(betatrimethylsilylpropionyl) terephthaloylferrocene; (2) 11,11 - bis(p - trimethyl-silylbenzoyl) adipylferrocene; (3) 11,11-bis-(gamma - trimethylsilylpropyl)p - xylylene-ferrocene; and (4) 11,11-bis(p-trimethylsilyl-benzoyl) terephthaloylferrocene.
