  Synthesis of sterically hindered aromatic dialdehydes

  摘要：

  A study was carried out on the formylation of a series of aromatic compounds containing two mesitylene or durene residues [dimesityl (I), dimesitylmethane (II), 1,2-dimesitylethane (III), 1,6-dimesitylhexane (IV), dimesityl sulfide (V), 1,1-dimesitylethylene (VI), 1,1-dimesityl-1-butene (VII), and didurylmethane (VIII)) by the action of dichloromethyl methyl ether (DCM) in the presence of AlCl3 and TiCl4. The corresponding dialdehydes are the major products. The formylation products when the reaction is carried out in the presence of AlCl3 in the case of (I) and (V) contain significant amounts of monoaldehydes, while partial cleavage of the substrates with the formation of products containing only one benzene ring is observed in the case of (II) and (VIII) in addition to formylation.

  A study was carried out on the formylation of a series of aromatic compounds containing two mesitylene or durene residues [dimesityl (I), dimesitylmethane (II), 1,2-dimesitylethane (III), 1,6-dimesitylhexane (IV), dimesityl sulfide (V), 1,1-dimesitylethylene (VI), 1,1-dimesityl-1-butene (VII), and didurylmethane (VIII)) by the action of dichloromethyl methyl ether (DCM) in the presence of AlCl3 and TiCl4. The corresponding dialdehydes are the major products. The formylation products when the reaction is carried out in the presence of AlCl3 in the case of (I) and (V) contain significant amounts of monoaldehydes, while partial cleavage of the substrates with the formation of products containing only one benzene ring is observed in the case of (II) and (VIII) in addition to formylation.
