Mercaptals (1), with low-cost and readily available Mn(OAc)2-KMnO4 system instead of the expensive Mn(OAc)3 as catalyst, reacted with diethyl phosphite to give novel 2-diethyl phosphate mercaptals (2a2d). Sequentially, compounds 2a2d reacted with diamines (3) to afford a series of 2-diethyl phosphate heterocyclic ketene amines (4) with good yields.

Key words: diethyl phosphite, manganese(II) acetate, free radical reaction, heterocyclic ketene aminal
