C-centered radicals. Intermolecular ‘tin-like’ radical reactions can subsequently be conducted under the most benign of conditions. The yields and efficiency of the processes are competitive and even superior in most cases to comparable conditions with tributyltin hydride. The use of air and electricity as the promotor (instead of a tin or other reagent) combined with the aqueous reaction media make this
Treatment of terminal acetylenes (R1CCH) with secondary or tertiary alkyl iodides (R2I) in the presence of triethylborane provides the corresponding alkenyl iodides (R1C(I)CHR2) in good yields.

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.
