O-Pivaloyl diphenyl­seleno­phosphinate

The title compound, C(17)H(19)O(2)PSe, was obtained in the reaction of the diphenyl­monoseleno­phosphinic acid ammonium salt with pivaloyl chloride. The P—Se bond length of 2.0769 (11) Å is normal, while the P—O bond length of 1.650 (3) Å is longer than in related O-alkyl and O-aryl derivatives. One...

description The title compound, C(17)H(19)O(2)PSe, was obtained in the reaction of the diphenyl­monoseleno­phosphinic acid ammonium salt with pivaloyl chloride. The P—Se bond length of 2.0769 (11) Å is normal, while the P—O bond length of 1.650 (3) Å is longer than in related O-alkyl and O-aryl derivatives. One phenyl ring is periplanar to the Se—P—C plane, while the dihedral angle between the two phenyl rings is ca 73°. The carbonyl group is in a synperiplanar position [torsion angle = 8.9 (6)°] to one of the methyl groups of the pivaloyl group. This is the first O-acyl derivative of diphenyl­monoseleno­phosphinic acid characterized by X-ray structural analysis.
