Tetrakis(dimethylamino)ethylene (TDAE) as a potent organic electron source: alkenylation of aldehydes using an Ni/Cr/TDAE redox system
摘要:
Tetrakis(dimethylamino)ethylene (TDAE) was found to be a potent organic electron source which could promote alkenylation of several kinds of aldehydes in the presence of a catalytic amount of NiBr2 and CrCl3. (C) 1999 Elsevier Science Ltd. All rights reserved.

The effect of solvents and additives on the stericcourse of [2,3]-Wittig rearrangement of the chiral 1,3-diphenyl-1-propenyloxy-2-propen-1-yl carbanion and its derivatives was examined on the basis of chirality transfer in intramolecular trapping.
