일반 설명
Triethylborane (Et3B) is an organoborane pyrophoric liquid. It is prepared on the plant scale by the reaction of AlEt3 and KBF4. Et3B is widely used as a precursor for the preparation of reducing agents such as lithium triethylborohydride and sodium triethylborohydride. It can also be utilized as an initiator in radical cyclization reactions.

Intermolecular hydroxyalkylation of alpha,beta-unsaturated imines involving Et3B-mediated regioselective alkyl radical addition and subsequent hydroxylation with molecular oxygen has been developed, in which N-borylenamine generated by trapping of the enaminyl radical with Et3B was a key intermediate in the proposed aerobic
