Silenes disilenes

The photochemistry of organosilicon compounds has been extensively studied, since many types of interesting reactive intermediates such as silylenes, silenes, disilenes and silyl...

Addition reactions to unsaturated silicon compounds (silenes, disilenes, disilynes) offer opportunities to form aminooligosilanes. An example is the reaction of Sekiguchi s disilyne with pyrrolidine, which gave the silicon version of an enamine. Further addition gave a geminal diaminotetrasilane (Scheme 26) [274],... 

After decades of unsuccessful attempted syntheses, Gusel nikov and Flowers in 1967 reported the first compelling evidence for the existence of silenes, compounds containing a double bond between silicon and carbon. This initiated a renewed interest in the synthesis and behavior of stable silenes,8 disilenes,b iminosilanes,c phosphasilenesd and their heavier homologs. 

The chemistry of silylene-metal complexes has developed in quite another direction, however, from reactions of disilyl-metal complexes, leading to complexes of otherwise unstable disilenes such as Me2Si=SiMe2. Molybdenum and tungsten complexes have been particularly well investigated by Berry and co-workers,103 and platinum complexes have also been isolated.104 Readers interested in this field are directed to a 1992 review of silylene, silene, and disilene-metal complexes.105...
