Selective Monoacylation of Symmetrical Diamines via Prior Complexation with Boron

(Equation presented) Pretreatment of a symmetrical primary or secondary diamine with 9-BBN prior to the addition of an acyl chloride significantly suppressed undesired diacylation, and the product of monoacylation predominated. The reactive preference is interpreted as the result of a selective deactivation of one nitrogen atom of the diamine by 9-BBN.

An Expedient Synthesis of Vicinal Diamines from Alkenes and Cycloalkenes

A new procedure for the facile preparation of various vicinal diamines is developed that utilizes diethyl N-(β-bromoalkyl)phosphoramidates 2 easily accessible by ionic addition of diethyl N,N-dibromophosphoramidate (DBPA) to alkenes and cycloalkenes 1.Cru
