Boron derivatives of dithiophosphoric acids
Abstract
The reactions of tetraphosphorus decasulfide 1 with trialkyl borates 2a,b and O-isobutyl diphenylborate 2c were studied. On the basis of these studies, a novel method of synthesizing S-boron derivatives of dithiophosphoric acids was developed. The use of low frequency ultrasonic irradiation (22 kHz, power 130 W) leads to a reduction in reaction temperature and time required for completion of the reactions studied. © 2000 John Wiley & Sons, Inc.
