ABSTRACT:
Method of producing compounds of the general formulain-line-formulae description="In-line Formulae" end="lead"?XPR2(OR1) Iain-line-formulae description="In-line Formulae" end="tail"?where X is chlorine, bromine or iodine and R1is an organic radical, by reacting compounds of the general formulain-line-formulae description="In-line Formulae" end="lead"?X2PR2 II,in-line-formulae description="In-line Formulae" end="tail"?in which X has the meaning given above and R2is an organic radical, with compounds of the general formulain-line-formulae description="In-line Formulae" end="lead"?R1OH III,in-line-formulae description="In-line Formulae" end="tail"?in which R1has the meaning given above, to give a mixture IV, in thata) the postreaction is carried out at a temperature of from 50 to 240° C. and a pressure of from 0.001 to 0.9 bar,b) from the mixture IV the compounds Ia are separated off from the compoundsin-line-formulae description="In-line Formulae" end="lead"?PR2(OR1)2 Ibin-line-formulae description="In-line Formulae" end="tail"?and, if appropriate, the compounds II andc) compounds Ib and, if appropriate, unreacted compounds II are returned to the synthesis stage.
