摘要：

1-alkyl- and 1-arylpyridylethenes were hydroformylated using rhodium catalysts in good yield, the regioselectivity the 1'-aryl-2-vinylpyridine hydroformylation occurs with the exclusive formation of the more branched aldehyde, whereas in the case of aryl substituted 1'-aryl-4-vinylpyridine only the more linear aldehyde was detected, Attempts to rationalize the results have been made.
