Abstract

This paper reports the synthesis of dineophyltin dihydride (3) following two procedures. The four steps synthesis starting from benzyl chloride and Sn was shown to be more convenient than the two step direct alkylation of SnCl4. The study of the free radical hydrostannation of mono-and disubstituted acetylenes with hydride 3 shows that they are stereoselective and that the stereoisomers obtained in higher proportion are stable and easily separated by ...
