(E)- and (Z)-Allylic tributyltins add to aromatic aldehydes to afford regioreversed alpha-adduct predominantly with almost complete retention of the stereochemistry of the allylic groups under photochemical conditions. The photoinduced single electron transfer mechanism is proposed.

A practical and scalable nickel‐catalyzed allylic stannylation of allyl acetates with Bu3SnOMe is described. A variety of acyclic and cyclic allyl acetates, even with base‐sensitive moieties, undergoes the stannylation by using NiBr2/4,4′‐di‐tert‐butylbipyridine (dtbpy)/Mn catalyst system to afford highly functionalized allyl stannanes with excellent regioselectivity and yields. Furthermore, the scope
