Abstract
Mild thermolysis of (2-pyridyl)(SiMe3)2CSbCl2 and [2-(6-Me)pyridyl](SiMe3)NAsCl2 affords, respectively, the chloro-bridged polymeric geminal C-centred distibine(III) complex [(2-pyridyl)(SiMe3)CSbCl]∞ 1 and the geminal N-centred arsenic(III) amide [{2-(6-Me)pyridyl}NAsCl]2 2; the proposed mechanism involves the elimination of Me3- SiCl and a [2 + 2] stereospecific cis-cycloaddition of the stibaalkene (SbC) and arsaimine (AsN) intermediates.Keywords
