Abstract

original image

Two Sn[N(SiMe3)2] moieties arranged trans, linked by a 1,4-diaminosubstituted cyclohexane or benzene ring describes the first heteroleptic bis(stannylene)s 1 and 2 (R = SiMe3), respectively; the bis(germylene) is isomorphous with 2. The replacement of the N(SiMe3)2 groups for aryloxy groups takes place on addition of Sn(OAr)2 to 1 and 2; surprisingly, the treatment of 2 with SnCl2 affords the redox products 3 and metallic tin.
