Axially chiral N,N-diethyl 2,6-disubstituted benzamides were stereo-selectively prepared utilizing planar chiral (arene)chromium complexes as an enantiomerically active form by following two methods. Ortho-lithiation of the enantiomerically pure planar chiral tricarbonyl(N,N-diethyl 2-methylbenzamid
In the 2H-chromene series, complexation of the aromatic ring with chromium tricarbonyl, under thermal conditions, is totally regioselective even when aromatic substituents are introduced on the pyran ring. The complexation stabilizes the open form of these photochromic compounds and reduces the ther
