Tributyl[2-(trimethylsilyl)-prop-2-enyl]stannane: A Highly Efficient Reagent for the Allylation of Radicals
Allylation rates of radicals with tributyl[2-(trimethylsilyl)prop-2-enyl]stannane (2) have been compared with the ones of the (prop-2-enyl)stannane (3) and [2-(methyl)-prop-2-enyl]stannane (4).The Me3Si substituent showed a rate-accelerating effect (4.2:1 to Novelty Socks 6.5:1) relati ve to the H-atom and the Me group for nucleophilic radicals.Wit
