Synthesis and Structure of an Azadistanniridine

Abstract

The stannanediyl (stannylene) 1 reacts with mesityl azide in a molar ratio of 2.5 : 1 to give the azadistanniridine 2. Compound 2 readily decomposes to 1 and the stannaneimine 3, which undergoes dimerization or is trapped in a [2 + 3] cycloaddition by mesityl azide (in excess) to give the dihydrostannatetrazole ( R′ = 2,4,6-(CF3)3C6H2).
