“…Early in the 1960s, silylenoids, analogues to carbenoids, were postulated as intermediates in some organosilicon reactions [1,2]. For example, in the reduction of dichlorodialkylsilanes R 2 SiCl 2 with alkali metals M to synthesize polysilanes, the reaction process was supposed experimentally as following: R 2 SiCl 2 +M -MCl R 2 SiMCl -MCl R 2 Si£º ( R 2 Si ) n silylenoid silylene polysilane…”

“…Early in the 1960s, silylenoids were postulated as intermediates in some organosilicon reactions. 5,6 Since then people tried to detect, even to obtain some silylenoid species as well as to probe into their structures and properties. [7][8][9][10][11][12][13] However, as a kind of very reactive species, the preparation of silylenoids is very difficult.…”
