The treatment of aromatic acetals with zinc and chlorosilane in the presence of potassium carbonate in toluene brought about facile and effective reductive coupling to give the corresponding coupling products. Copyright
Reductive homocoupling of acetals derived from aromatic aldehydes with aluminium/lead bimetal redox system

Various bimetal redox systems Al/MXn (M=V, Nb, Co, Hg, Ge, Sn, Pb and Bi) were found efficient electron sources to promote the reductive coupling of benzaldehyde dimethylacetal into 1,2-diphenyl-1,2-dimethoxyethane 2a.Among these combinations the bimetal system Al/PbBr2 gives the best results with dimethylacetals derived from aromatic aldehydes leading to the corresponding 1,2-diaryl-1,2-dimethoxyethanes 2.On the other hand the reductive dimerization of acetals derived from aliphatic aldehydes does not take place with the previous bimetal redox systems Al/MXn, meanwhile under the same conditions the mixed acetals (α-methoxycarbamates) 4a,b lead to the corresponding carbamates 5a,b by hydrogenolysis of the carbon-oxygen bond (N-C-OMe).
