The quantitative conversion of the tertiary stannane (n-Bu) 3SnH (2) into (n-Bu) 6Sn2 (4) was achieved by heating the neat hydride material under low pressure or under closed inert atmosphere conditions. A 31% conversion of Ph3SnH (3) to Ph6Sn2 (5) was also observed under low pressure; however, under closed inert atmosphere conditions afforded Ph4Sn (6) as the major product. A mixed distannane,(n-Bu) 3SnSnPh3 (7), can also be prepared in ...
