Anomalous rearrangements in the reaction of acylpolysilanes with TMSNTf2
Abstract
Reaction of acylpolysilanes with silylbistriflimides (R3SiNTf2) leads to novel silanols via a pathway involving two 1,2-migrations of Me3Si groups from silicon to carbon and one migration of a R3SiO unit from carbon to silicon; the X-ray structure of one example is reported.
