文摘
An anthryl-substituted exocyclic silene, 3-silylene-2-silaaziridine, was synthesized by isomerization of the corresponding disilacyclopropanimine. The UV鈥搗is spectrum of the silene shows a distinct intramolecular charge transfer (ICT) transition from the 蟺 orbital of the Si鈺怌 double bond to the 蟺* orbital of the anthryl moiety. The relatively high-lying 蟺(Si鈺怌) orbital of the 3-silylene-2-silaaziridine moiety and the low-lying 蟺* orbital of the anthryl group would be responsible for the distinct ICT band.
