| titleOfInvention | PROCESS FOR THE PREPARATION OF THIOPHOSPHORIC ACID-O, O-DIALKYLESTER |
| abstract | The invention relates to a one-pot reaction for the preparation of Thiophosphorigsaeure-O, O-dialkyl esters of elemental phosphorus. The aim of the invention is to produce thiophosphoric acid O, O-dialkyl esters in high yields and in tolerable reaction times. According to the invention, elemental white phosphorus is reacted with tetrachloromethane, alcohols, sodium alcoholates and subsequently with hydrogen sulphide in the presence of weak bases as catalysts at temperatures of 0 to 60 ° C. in a solvent or solvent mixture. Thiophosphoric acid O, O-dialkyl esters serve as intermediates in the preparation of insecticides, acaricides and nematicides. |
