FIELD: chemistry.
SUBSTANCE: invention relates to a method for synthesis of N,N-dialkylamidofluoroanhydrides of alkyl(aryl)phosphonous acids of general formula: RP(NR2')F, where R=CH3, C2H5, i-C3H7, C6H5; NR2'=(CH3)2N, (C2H5)2N, (i-C4H9)2N, (C4H9)2N,
and can be used in organic synthesis. Method involves treatment of alkyl(aryl)difluorophosphines of formula RPF2 with trimethylsilyl amines of general formula (CH3)3Si(NR'2), where NR2'= (CH3)2N, (C2H5)2N, (i-C4H9)2N, (C4H9)2N,
at -30-20°C for 30-60 minutes.
EFFECT: design of a novel method for synthesis of compounds needed in organic synthesis.
