    Abstract: A ketosilane of formula is prepared by reacting a silyl acyl chloride of formula with an alkylaluminium halide of formula R1AlY2, where Y is a halide substituent; R is a halogen-substituted or halogen-unsubstituted monovalent hydrocarbon radical, or an alkyl radical substituted with an OR11 group, where R11 is a monovalent hydrocarbon radical free of aliphatic unsaturation or a monovalent radical free of aliphatic unsaturation and consisting of C, H and O atoms with each O atom attached to two carbon atoms; R1 is an alkyl radical, m=0, 1, 2 or 3, a=integer from 2 to 10 and p=0, 1, 2 or 3 and is no larger than m. Ketosilanes of formula XnR3- nSi(CH2)aCOR1 where X is a halogen atom, an alkoxy radical, aryloxy radical, acyloxy radical or a substituted or unsubstituted amine radical, n=1, 2 or 3 are claimed per se. Cyclic organopolysiloxanes of formula (R[R1CO(CH2)a]SiO)x where x = an integer from 4 to 16 are also claimed per se. Examples describe the preparation of (1) 5-(trimethylsilyl)-2-pentanone and a disiloxane of formula [CH3CO(CH2)3Si(CH3)2]2O (2) gamma - (trimethylsilyl) - 3 - hexanone, (3) a disiloxane prepared from gamma (chlorodimethylsilyl) butyryl chloride, (4) beta-(dichloromethylsilyl)-2-butanone and a cyclic polysiloxane of formula (R1112SiO)x, where x=4 to 16 and R111 is a monovalent organic radical, prepared from it, (5) dimethyl-polysiloxane and but-3-one-yl methylpolysiloxane prepared from 4 - (dichloromethylsilyl) - 2 - butanone and dimethyldichlorosilane and (6) 4 - (chlorodimethylsilyl) - 2 - butanone and gamma- (ethoxydimethylsilyl) 2-pentanone.

    Abstract: Metallocenes containing at least one nuclear substituent of formula A(R)2Si-R1-Y-wherein R is H, halogen, alkoxy, hydrocarbon, halohydrocarbon, cyanoalkyl or fluoroalkyl (see Division C3), may be used as lubricants.ALSO:The invention comprises metallocenes having at least one monovalent radical of the formula A(R)2Si-R1-Y-bonded to at least one of the two cyclopentadienyl nuclei, which may also be substituted by aryl, hydroxyaryl, cycloaliphatic, nitroaliphatic, acyl, arylaryl, sulpho, carboxyaryl, nitroaryl, haloaryl, haloaliphatic groups; wherein R is a hydrogen, halogen, alkoxy, hydrocarbon, halohydrocarbon, cyanoalkyl or fluoroalkyl monovalent radical, A is an R radical or hydroxy, R is a divalent hydrocarbon or halohydrocarbon radical of at least two carbon atoms, Y is carbonyl, carbinol, methylene, carbamino, or carbazido group. Specified transition metals forming the metallocenes are titanium, vanadium, chromium, manganese, iron, cobalt, nickel, zirconium, columbium, molybdenum, technetum, ruthenum, rhodium, palladium, hafnium, tantalum, tungsten, rhenium, osmium, indium and platinum. The compounds may be substituted in both rings. Many compounds are specified. Compounds wherein Y is a carbonyl radical are prepared by reacting R3Si-R1-CO-X, wherein X is a halogen atom with a metallocene in the presence of a Friedel-Craft catalyst, and hydrolysing the product; the carbonyl group may then be modified to the other specified Y groups by conventional reactions. Compounds in which both rings are identically substituted may be prepared by reacting a metallated cyclopentadiene with a silyl chloro-hydrocarbon and reacting the product first with a metal e.g. lithium, and then with the appropriate metal halide. The silyl-organo-carboxylic halides, R3Si-R1-CO-X, may be prepared either by alkylation of a malonic ester with a haloalkyltrialkylsilane followed by halogenation of the resulting acid, or by alkylating a b -cyanoalkyl-trihalosilane followed by hydrolysis. Compounds may be hydrolysed to siloxanes, including disiloxanes containing organosiloxane and metallocene units. A typical Example (1) describes the preparation of ; in another Example (13) a polydimethylsiloxane is mixed with product of (1), fumed silica and benzoyl peroxide and the mixture cured. Uses.-Heat stabilizers for organopolysiloxane elastomers, U.V. absorbers, anti-knock compounds, anti-oxidants, lubricants, smoke eliminators, dyestuffs, photographic developers, vulcanization accelerators, fuel additives, metalplating reagents, polymerization catalysts (for polyethylene, curable silicones, alkyd resins and drying oils) medicinals, fungicides, pesticides, agricultural chemicals, damping fluids; vinyl-containing metallocenes may be polymerized alone or with other monomers (e.g. chloroprene, styrene, HCHO).

Q is a gp. (M)3-a GaSiR"-). Cpds (I) are prepared by distillation of (II); (III) by reacting (M)3-aGaSiR"X where X is halogen with a metal isocyante; (II) as for (III) only together with a cpd. ROH. The cpds above are used for caulking compsns, glass finishing and metal treatment and are much less, susceptible to hydrolysis compared with cpds where the gps are directly linked.
