Participants

Reaction Steps

Diphenylmethylamine (4.00 ml) and cyclopentanone (2.06 ml) were stirred at 120° C. for 3 hours, and then the mixture was returned to room temperature and added with tetrahydrofuran (2 ml) and phosphinic acid (1.8 g). The mixture was stirred at room temperature for 3 minutes, and then allowed to stand for 17 hours. Water (20 ml) was added to the reaction system, and the insoluble solid was collected by filtration and washed with tetrahydrofuran, and then dried to obtain crude 1-(diphenylmethylamino)cyclopentylphosphinic acid (1.53 g). This compound was subjected to the measurement of molecular weight and then used in the following reaction.
