Abstract: is introduced into a soln in an inert organic solvent of PBr5 and/or PBr3 and Br at 0.6 1/min per gram atom of P i n the soln. During the reaction an excess of Br of 2-50 wt.% over the required theoretical for PBr5 formation is maintained and introduction of NH3 is kept up until at least the stoichiometric quantity for the reaction has been added and the (NPBr2)3 isolated from the reaction mixt. Prod. is used in semiconductor mfre.

Abstract: Cpds. of formula (I):- (R)3P=N- P(R)2=N nP(X)(R2) (I), (where X is O or S; each R is halogen, 1-4C alkoxy; NR2R3 in which where R2 is H or 1-4C alkyl, and R3 is 1-6C alkyl or phenyl opt. substd. by halogen or NO2, or R4R5P(X1)S- (in which X1 is O or S, and R4 and R5 are 1-4C alkoxy; n = 0,1 or 2; >=1 R is R3R5P(X1)S or NR2R3, and the no. of same substituents R is =2n + 4) are insecticides. (I) are pref. prepd. by reacting (I; R = Cl) with a 1-4C alkanol, HNR2R3 and/or R4R5P(X1)SM (where M is NH4, tetraalkylammonium, Na, K or 1/2 equiv. of an alkaline earth metal).
