Linear 2,2-Diaryl-Substituted Trisilanes: Structure and Photolysis to Disilenes

摘要

Synthesis of the new disilene, E/Z-IsMesSi=SiIsMes (1) is reported; the isomerIs2Si=SiMes2 (2) was obtained by photolysis of a mixture of Mes2Si(SiMe3)2 (3) and Is2Si(SiMe3)2. Isomerization of 1 right left arrows 2 does not take place up to 80 deg C. X-ray crystal structures are reported for trisilanes 3, IsMesSi(SiMe3)2 (4), and 5.
