General description
"Reagent of the Year 1990"
Other Notes
Efficient mediator in organic radical reactions that rivals tributyltin hydride. It is a superior reagent for ecological and practical reasons giving less unwanted reduction products9,10,4,11; In can be used in catalytic amounts in the presence of sodium borohydride; Starting material for various tris(TMS)3silyl compounds
Application
Super Silyl Protecting GroupsUsed in:
• Hydrosilylations1
• Radical reactions2
• Reductions of acid chlorides3
• Reductions of carbon-halogen bonds4
• Hydrosilations of carbonyls5
• Another common application involves the use of the tris(trimethylsilyl)silyl (TTMSS, or super silyl) group when complexed with transition metals and main group elements6,7
• More recently, the super silyl group is being utilized in carbon-carbon bond forming reactions8
