Diorganostannide dianions (R2Sn2-) as reaction intermediates revisited: In situ 119Sn NMR studies in liquid ammonia

It has frequently been proposed that diorganostannide dianions, SnR 22-, form during reactions of dihalodiorganostannanes or dihydrodiorganostannanes with sodium in liquid ammonia. The formation of this intermediate has been advanced to be an important step in the synthesis of a wide range of organostannanes. Here we report 119Sn NMR investigations in liquid NH3 of reaction intermediates that formed in situ during the conversions of dichlorodiphenylstannane, dihydrodiphenylstannane (diphenylstannane), dideuterodiphenylstannane, and dichlorodibutylstannane, respectively. This study revealed that the proposed SnR22- dianion was not present, but tetraorganodistannides, (R2Sn-SnR2)2-, and hydrodiorganostannides (tin hydrides), R2SnH- (or R 2SnD-, respectively), were detected instead.
