Disproportionation of Sn(ii){CH(SiMe3)2}2 to Sn(iii){CH(SiMe3)2}3 and Sn(i){CH(SiMe3)2}: characterization of the Sn(i) product

Half a century after the photolytic disproportionation of Lappert's dialkyl stannylene SnR2, R = CH(SiMe3)(2) (1) gave the persistent trivalent radical [SnR3], the characterization of the corresponding Sn(i) product, SnR is now described. It was isolated as the hexastannaprismane Sn6R6 (2), from the reduction of 1 by the Mg(i)-reagent, Mg(BDIDip)(2) (BDI = (DipNCMe)(2)CH, Dip = 2,6-diisopropylphenyl).
