    Abstract: The invention relates to aqueous dispersions comprising a polyurethane, produced from a) diisocyanates, b) diols, of which b1) 10 to 100 mol. %, relative to the total amount of diols (b), have a molecular weight of 500 to 5000 and b2) 0 to 90 mol. %, relative to the total amount of diols (b), have a molecular weight of 60 to 500 g/mol, c) various monomers from amongst the monomers (a) and (b) with at least one isocyanate group or at least one group reactive towards isocyanate groups, with furthermore, at least one hydrophilic or potentially hydrophilic group, by means of which the aqueous dispersibility of the polyurethane is affected, d) optionally additional polyfunctional compounds different from the monomers (a) to (c), said functions being alcoholic hydroxy groups, primary or secondary amino groups or isocyanate groups and e) optionally additional monofunctional compounds different from the monomers (a) to (d), said function being an alcoholic hydroxy group, a primary or secondary amino group or an isocyanate group. Said dispersions may be obtained by reaction of the monomers a), b), c) and optionally d) and e) in the presence of a caesium salt.

    Abstract: Grignard compounds (I) containing functional reactive substituents are new. Aromatic Grignard compounds (I) are new: z = 0 or 1; X = halo or R ; A, B, D and E = CH; CR ; N; P; or CR ; F = O, S, NR , CR or CR when z = 0 and CH, CR , N, P or CR when z = 1; or two adjacent symbols A-F form an optionally substituted aromatic, saturated or partly unsaturated 5-8 membered ring containing 1 or more hetero atoms, e.g. O, N, S or P; R = COOR ; CN; CONR R '; or halo; R = 1-10C alkyl, 3-10C cycloalkyl, 1-4C alkylaryl or 1-4C alkylheteroaryl (each optionally substituted) or R ; R = H; 1-10C alkyl, 3-10C cycloalkyl, 1-4C alkylaryl or 1-4C alkylheteroaryl (each optionally substituted); R '; or R ; R ' = H; 1-10C alkyl, 3-10C cycloalkyl, 1-4C alkylaryl or 1-4C alkylheteroaryl (each optionally substituted); or R ; R = 1-10C alkyl, 3-10C cycloalkyl, 1-4C alkylaryl or 1-4C alkylheteroaryl (each optionally substituted); or halo; R = solid carrier; R = 1-10C alkyl, 3-10C cycloalkyl, 1-4C alkylaryl or 1-4C alkylheteroaryl (each optionally substituted and optionally bonded via carbonyl); or -SO2-aryl; Not more than three of the variables A-F are heteroatoms. An Independent claim is also included for the preparation of compounds (I).

    Abstract: Optionally carrier-bound aromatic or heteroaromatic Grignard reagents (I) are new. Grignard reagents of formula (I) are new. z = 0 or 1; X = halo or R2; A2-A5 = CH, CR2, N, P or CR3; A1 = O, S, NR6, CR2 or CR3 if z = 0; or CH, CR2, N, P or CR3 if z = 1; R1 = COOR2, CN, CONR3R'3 or halo; R2 = optionally substituted 1-10C alkyl, 3-10C cycloalkyl, (1-4C) alkylaryl, (1-4C) alkylheteroaryl or R5; R3 = H, optionally substituted 1-10C alkoxy, 3-10C cycloalkoxy, (1-4C) alkylaryloxy, (1-4C) alkylheteroaryloxy, R'3 or R5; R'3 = H, optionally substituted 1-10C alkyl, 3-10C cycloalkyl, (1-4C) alkylaryl, (1-4C) alkylheteroaryl or R5; R5 = solid carrier; R6 = optionally substituted 1-10C alkyl, 3-10C cycloalkyl, (1-4C) alkylaryl, (1-4C) alkylheteroaryl, optionally substituted (1-10C) alkylcarbonyl, (3-10C) cycloalkylcarbonyl, (1-4C) alkylarylcarbonyl, (1-4C) alkylheteroarylcarbonyl or arylsulfonyl; A1 + A5 = optionally substituted aromatic, saturated or partially unsaturated 5-8 membered ring, optionally containing one or more heteroatom(s) such as O, N, S or P; and provided that not more than 3 of A1-A5 are heteroatoms. AN Independent claim is included for the preparation of (I).
