Abstract

The reactions of 6-bromo-4-(l', l'dimethylethyl) hexanal (4), 5bromo-3-(l', l'-dimethylethyl) pentanal (ll), and 5-bromo-4-(l ', l'-dimethylethyl) pentanal (17) with tributylstannane have been investigated in detail. The major producta are the debrominated aldehydes and cycloalkanols which arise from the cyclization of the intermediate u-formyhlkyl radicals. The stemxhemical outcome of the cyclization of thw radicals is dependent on the etanuane ...
