Abstract
The present invention relates to a process for the production of monoalkyltin trihalides of the formula RSnHal, in which R=alkyl or cycloalkyl and Hal=Cl. Br or I. Said process comprises contacting the corresponding alkene or cycloalkene, stannous halide SnHal, 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 RSnHalfrom monoalkyltin trihalides of the formula RsnHal'. in which R=alkyl or cycloakyl and Hal=Cl, Br or I. Said process comprises contacting monoalkyltin trihalides RsnHaland Sn metal, optionally thereafter isolating the dialkyltin dihalides RSnHalfrom the medium.
