Unimolecular chain transfer (UMCT) reactions: concepts, preliminary results with silicon hydrides, and future potential
Abstract
Most radical reactions are conducted by chain methods that have bimolecular chain transfer steps. It is proposed that unimolecular chain transfer (UMCT) reactions should have advantages for conducting difficult radical transformations. The concepts of the UMCT method are illustrated with allyltributylstannane, and the first examples of UMCT reactions of silicon hydrides are introduced. Examples of bimolecular reactions conducted with silicon hydride UMCT reagents are provided, and the potential of the UMCT method is discussed.
