Synthesis, Characterization, and Complexation of an Unusual P₂Si₂ Bicyclobutane with Butterfly‐Structure: 2,2,4,4‐Tetramesityl‐1,3‐diphospha‐2,4‐disilabicyclo[1.1.0]butane

Abstract

Reaction of white phosphorus with dimesityldisilene in toluene at 40°C affords an 87% yield of the P2Si2 bicyclobutane 1, which reacts further with [(PPh3)2Pt(C2H4)] to give hetero[1.1.1]propellane 2.
