Abstract

The unsymmetrical diorganomanganeses (II)(R 1 R 2 Mn) and magnesium triorganomanganates (II)(R 1 2 R 2 MnMgX) reacted with 2-cyclohexen-1-one to produce the 1, 4-addition products in moderate to good yields. The approximate reactivity order obtained from the product distribution was CH 2= CHCH 2> PhS> n-Bu> Ph> Me, Me 3 SiCH 2, nC 6 H 13–C≡ C. In contrast, the reactivity order for the addition of these reagents to ...
