Synthesis of Acyl Phosphoramidates Employing a Modified Staudinger Reaction

A one-step synthesis of acyl phosphoramidates from a variety of functionalized acyl azides has been developed employing trimethylsilyl chloride as an activating agent in a modified Staudinger reaction. The methodology was further adapted to include the in situ generation of the acyl azides from a diverse selection of carboxylic acids and hydrazide starting synthons. The reaction scope was extended to include the synthesis of imidodiphosphates and the natural product Microcin C.

Flame retardant cotton fibers produced using novel synthesized halogen-free phosphoramide nanoparticles

Flame retardant cotton fibers were successfully produced using five new nanosized phosphoramide compounds synthesized by ultrasonic method. The 1H NMR spectra of compounds 1-3 illustrate 3J(H,H)cis and 3J(H,H)s

Stereoselectivity in Fragmentation and Rearrangement of α-Hydroxyiminophosphinates and -phosphonates. A Synthetic Approach to Acylphosphon- and phosphor-amidates. Crystal Structures of Methyl (E)-α-Hydroxyiminobenzylphenylphosphinate and Methyl Benzoylphenylphosphonamidate

Reaction of methyl benzoylphenylphosphinate 1 with hydroxylamine gave methyl α-hydroxyiminobenzylphenylphosphinate 2 as a mixture of E and Z isomers with the E isomer predominating.Pure (E)-2 when heated gave methyl N-benzoylphenylphosphonamidate 3 as the sole product.In contrast, (Z)-2 when heated gave, as a result of fragmentation, mainly methyl hydrogen phenylphosphonate 4 and benzonitrile, together with methyl N-phenylcarbamoylphenylphosphinate 5 as the minor product; the latter results from Beckmann rearrangement of (Z)-2.Analogous behaviour is exhibited by the two geometrical isomers of dimethyl α-hydroxyiminobenzylphenylphosphinate (E)-2 and methyl benzoylphenylphosphonamidate 3 are reported.
