PREPARATION OF TRANSITION METAL COMPLEXES OF CHIRAL DERIVATIVES OF ACETOACETIC ACID - TETRAALKYLAMMONIUM TETRACHLOROMETALLATES AS AN ORGANIC SOURCE OF METALS

摘要

Bis(benzyltrimethylammonium) tetrachlorocuprate, tetrachlorocobaltate and hexachlorodiferrate react in organic solvents with alkaline salts of CH3COCH2CO-X(c) [X(c)-H = (d)-menthol, (4S)-4-benzyl-2-oxazolidinone and (2R)-bornane-10,2-sultam] to give homochiral beta-dicarbonyl metal complexes.
