Acylation benzoylation

The reaction (CO)5Mn(COCgH5) with CHjLi is known . The benzoyl complex undergoes nucleophilic attack at coordinated CO to give an anionic cis-acyl, benzoyl complex that can be isolated as its [Me4N] salt ... 

Scheme 9. Acyl (benzoyl in this case)-transfer from a glycosyl donor (18) to the acceptor (MPEG-DOXOH), accompanied by formation of 2-OH glycosides (21ab) and (I >2)-linkcd oligosaccharides 22.

We have made acyl, benzoyl and butyryl esters/amides of zein. These products were washed with ethyl acetate to remove unreacted acid chlorides or anhydrides. The NMR of these confirmed the acylation. When dianhydride, 1,2,4,5-benzenetetracarboxylic dianhydride (BTCD), was reacted in various levels, slightly crosslinked to highly crosslinked products were obtained. The highly crosslinked product gelled out of the DMF solution. However, the slightly crosslinked (10Jl) zein was still soluble in DMF and we could make bars out of them by compression molding.
