[1 + 4]-Cycloaddition of a stable silylene to 2,4,6-tri-tert-butyl-1,3,5-triphosphabenzene
Abstract
The stable bis(amino)silylene Si[(NCH2But)2C6H4-1,2] 1 undergoes [1 + 4]-cycloaddition with 2,4,6-tri-tert-butyl-1,3,5-triphosphabenzene 2 to afford compound 3: the molecular structure of 3 is supported by NMR spectroscopic data and confirmed by a single crystal X-ray diffraction study.
