Title (EN) PROCESS FOR THE PREPARATION OF MONOALKYLTIN TRIHALIDES AND DIALKYLTIN DIHALIDES
(FR) PROCEDE DE PREPARATION DE TRIHALOGENURES DE MONOALKYLTINE ET DE DIHALOGENURES DE DIALKYLTINE
Abstract:
(EN) The present invention relates to a process for the production of monoalkyltin trihalides of the formula RSnHal3, in which R = alkyl or cycloalkyl and Hal = Cl. Br or l. Said process comprises contacting the corresponding alkene or cycioalkene, stannous halide SnHal2, hydrogen halide HHal and optionally Sn metal, in the presence of at least one transition metal-based catalyst, thereafter isolating the monoalkyltin trihalides from the medium. The present invention also relates to a process for the production of dialkyltin dihalides of the formula R2SnHal2 from monoalkyltin trihalides of the formula RsnHal3,. in which R = alkyl or cycloalkyl and Hal = Cl, Br or l. Said process comprises contacting monoalkyltin trihalides RsnHal3 and Sn metal, optionally thereafter isolating the dialkyltin dihalides R2SnHal2 from the medium.
(FR) L'invention porte sur un procédé de production de trihalogénures de monoalkyltine de formule RSnHal3, dans laquelle: R = alkyle ou cycloalkyle et Hal = Cl, Br ou l, consistant à mettre en contact l'alcène ou le cycloalcène correspondant, l'halogénure d'étain SnHal2, l'halogénure d'hydrogène Hhal, et facultativement du Sn, en présence d'au moins un catalyseur à base de métal de transition, puis à isoler le trihalogénure de monoalkyltine du milieu. L'invention porte également sur un procédé de production de dihalogénures de dialkyltine de formule R2SnHal2 à partir de trihalogénures de monoalkyltine de formule RSnHal3 dans laquelle: R = alkyle ou cycloalkyle et Hal = Cl, Br ou l, consistant à mettre en contact le trihalogénure de monoalkyltine RsnHal3 et du Sn, puis facultativement à isoler le dihalogénures de dialkyltine de formule R2SnHal2 du milieu.
