Sodium hydride → Tributyl-cyclobutoxymethyl-tin

Participants

Reaction Steps

To a solution of 2.3 g of cyclobutanol in 60 mL of dry THF was added 624 mg of 98% sodium hydride. After stirring 2 h, 5.6 g of iodomethyl tributyltin (prepared as described by Seitz et al 1983 Synthetic Comm. 13 129) was added and the reaction mixture was stirred at room temperature for 48 h, and then poured onto water and extracted with hexanes. The extracts were washed with brine, dried and evaporated to a crude product that was purified by flash chromatography (hexanes then 67% ethyl acetate/hexanes eluents) to afford 1.64 g of tributyl (cyclobutyloxymethyl)tin as a colorless oil.
