This class of amides has been made enantio-selectively - albeit in low yield and low ee -by an ortholithiation reaction (Scheme 10). More successful is Uemura s demonstration [19] that the arene-chromium tricarbonyl complex chemistry that works with atroposelectivc biaryl couplings is also successful with atropose-lective amide-forming reactions (Scheme 11).

Yet another major advance in arene-metal chemistry was made in 1957 by Fischer and Ofele 95) y who found that a sealed tube reaction involving chromium hexacarbonyl, bis(benzene)chromium, and benzene produced the half-sandwich compound benzene-chromium tricarbonyl (XXVII). [Pg.511]

Chiral Catalysts Containing Group 6 Metals (Cr, Mo, and W). Although all the three metals have important role in organometallic chemistry (eg, carbonyl complexes), their catalytic properties are scarcely investigated in the past few years. The tricarbonyl(jj -arene)chromium structural unit (see Fig. 16)... [Pg.694]

An overview of the effect of catalyst in the reaction of arenes with chromium hexacarbrmyl has been published. The reactivity of 17-, 18-, and 19-etectron catkMis generated electrochemically from mesitylene-tungsten tricarbonyl has been examined. The gas phase ion chemistry of a range of arene tricarbonylchromium complexes has been investigated by F.T. mass spectrometry. An improved synthesis of substituted naphthalene chromium carbonyls has appeared. ... [Pg.341]
