  Reversible nature of the opening of the tetrahydrofuran ring of diphenyl(2-tetrahydrofurylmethyl)phosphine oxide by the diphenylphosphinite anion

  摘要：

  The reaction of diphenyl (2-tetrahydrofurylmethyl)phosphine oxide with diphenylphosphonous acid in DMSO in the presence of KOH proceeds with opening of the tetrahydrofuran ring and leads to 4,5-bis(diphenylphosphinyl) pentanol. This product is converted to the starting oxide upon the reaction with diphenylvinylphosphine oxide. 4,5-Bis(diphenylphosphinyl) pentanol is converted to the corresponding tosylate. The action of alcoholates on this tosylate gives 1-ethoxy-4,5-bis(diphenylphosphinyl)pentane and 1-butoxy-1,5-bis(diphenylphosphinyl)pentane.
