Compsns. contng. cpds of formula:- (where Y = Cl, Or3; X = Cl, Br; R1, R2, R3 = alkyl -(opt. substd. by halo, alkoxy, alkenyloxy, phenoxy, cycloalkyl, alkylthio, alkoxycarbonyl, heterocyclic gp., dialkylammonio, trialkylammonio), opt. halo substd. alkenyl, alkynyl, cycloalkyl, phenyl (opt. substd. by cyano, nitro, alkyl, haloalkyl, alkoxy, alkylthio, alkanoyl or alkoxycarbonyl), benzyl (opt. substd. by alkyl, alkoxy halo), -COR4; R4 = alkyl (opt. substd. by halo, cycloalkyl, phenyl (opt. substd. by alkyl, alkoxy, halo), alkoxy, alkoxycarbonyl, benzoy), phenyl (opt. substd. by halo, lower alkyl, lower alkoxy), 5-6 membered heterocyclic, alkenyl (opt. substd. by halo, cycloalkyl, phenyl (opt. substd. by halo, alkyl, alkoxy)), alkenyl or R1 and R2 nopt. when they are -COr4) together with the Si atom form an opt. unsatd. heterocyclic gp.). Cpds. where (a) X = Br, and (b) where X = Cl and unsubstd. alkyl gps. contain 6-18C atoms are novel. |
