Synthesis and Characterization of an Isolable Base-Stabilized Silacycloprop-1-ylidene

摘要

The chemistry of stable silylenes has been the subject of considerable research since the isolation of silicocene and N-heterocyclic silylene. To date, several stable silylenes, including kinetically stabilized dialkylsilylene, have been synthesized and their chemical properties have been extensively investigated. A novel silylene stabilized by ylidic carbon centers has also recently been reported. However, the structural modifications of stable silylenes are still far more limited than those of their lighter analogues, the carbenes.
