H. Bricout et al., FURTHER DEVELOPMENTS IN METAL-CATALYZED C-C BOND-CLEAVAGE IN ALLYLIC DIMETHYL MALONATE DERIVATIVES, Tetrahedron letters, 38(6), 1997, pp. 1053-1056
The use of a catalytic amount of nickelbis(1,4-bis(diphenylphosphino)b
utane) in DMF enables the activation of the C-C bond in dimethyl allyl
malonate derivatives to proceed under rather smooth reaction condition
s, without added nucleophile. Several examples like isomerization of s
ubstituted-allyl malonate derivatives, racemization of chiral products
, but also a synthetic application as an inverse disproportionation re
action are described. (C) 1997, Elsevier Science Ltd.
