Trialkyl Phosphites

Diazoketones 1, 8, 10 and 14 react with trialkyl phosphites to give different products depending upon the structure of the diazo compound, the type of the solvent and the nature of the phosphite ester used. Possible reaction mechanisms are discussed and the structural assignements are based on analytical, chemical and spectroscopic results.

Dimethyl Phosphite

Diethyl phenylphosphonite and ethyl diphenylphosphinite react with 2-benzylideneindan-1,3-dione(1) to give colourless addition compounds (6) and (8) respectively. The reaction of diethyl methyl phosphite and ethyl dimethyl phosphite with (1) leads to the formation of the corresponding phosphonates (9) and (11). Possible reaction mechanisms are considered and the structural assignments are based on chemical and spectroscopic evidence.
