Thermal Equilibrium between a Lattice-Framework Disilene and the Corresponding Silylene

Abstract

The existence of the thermal equilibrium between 2,3,4,6,7,8,2‘,3‘,4‘,6‘,7‘,8‘-dodeca-tert-butyl[5,5‘]bi{1,5-disilatricyclo[4.2.0.01,4]octylidene}-2,7,2‘,7‘-tetraene and the corresponding silylene was revealed by trapping experiments. The equilibrium was investigated by DFT calculations.
