Organotins organomagnesiums

S. from Organotin Hydrides with Organomagnesium-Halide Reagents... [Pg.519]

The organotin-Mg compound BujSnMgCl finds application in synthetic chemistry . It is obtained from BujSnH with organomagnesium-halide reagents (R = i-Pr, s-Bu, t-Bu, c-CgHn) ... [Pg.519]

The most common way to get organotin-Mg compounds is from organotin hydrides with an organomagnesium-halide reagent. The 1 1 reaction of PhjSnH with EtBrMg NEtj in Et20 at —15 to 0°C results in selective hydrostannolysis of the Mg—C bond as evidenced by the quantitative formation of ethane ... [Pg.520]

The normal targeted products of reactions between tin (IV) halides and organomagnesium or organolithium reagents are the tetraorganotins, as it is difficult to control alkylation sufficiently well to a lower extent. However, controlled reactions can be achieved in certain cases, e.g. when bulky groups are present (such as cyclohexyl) or when an organotin halide product can be stabilized by chelation (equation 10). [Pg.4873]
