## Abstract Regioselectivities in Michael‐type reactions of organoaluminium and organotitanium reagents with sterically hindered carbonyl compounds 1 and 5 concerning 1,2‐ versus 1,4‐addition were determined. Throughout this investigation Me~3~Al/cat. Ni(acac)~2~ was found to be the most useful rea
