Simple 2° - and 3° -alkyl iodides add smoothly to electron deficient alkynes under standard atom transfer conditions 10% Bu3SnSnBu3, sunlamp photolysis. Mechanistic experiments help to interpret stereochemical and yield trends, and a new model for atom abstraction reactions of rapidly inverting a-vinyl radicals is proposed.
