Abstract

The room-temperature reactions of stannocene, Cp*2Sn, with a range of primary phosphines, RPH2, result in diphosphanes [RP(H)P(H)R]. The reactions involving Cp*2SnCl2, however, result in catalytic dehydrocoupling; the first example of main group metal catalysed dehydrocoupling to be identified.
