摘要
Stable vinylidene analogue: The synthesis of the first representative of a new compound class of low-valent Group14 elements, namely silagermenylidene A, is achieved by reduction of Tip2SiCl2 and NHC×GeCl2 (Tip=2,4,6-iPr3C6H2; NHC=1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene). The potential of A as a synthon is demonstrated by the formal [2+2] cycloaddition with phenylacetylene to afford NHC-stabilized cyclic germylene B. Copyright © 2013 WILEY-VCH Verlag GmbH & Co.
