Abstract

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(BDI^Dip)₂ (BDI = (DipNCMe)₂CH, Dip = 2,6-diisopropylphenyl).
