WebTriphenylphosphine selenide is an organophosphorus compound with the formula 3PSe. It is a white solid which is soluble in most organic solvents. The compound is used in the … WebThe molecule has almost ideal C3 symmetry. The C–P–C angle is the smallest reported for a tertiary phosphine selenide. The average P–C bond length [1.778 (6)Å] and the P–Se bond length (2.094 Å) are both considerably shorter than found in other arylphosphine selenides.
WebA co-crystalline adduct consisting of a phosphinine selenide and an organohalide was obtained by slow evaporation of the solvent from a mixture of 2,6-bis(trimethylsilyl)phosphinine selenide and 1,4-diiodotetrafluorobenzene (1,4-TFDIB). The crystallographic characterization of the product shows π-π … Triphenylphosphine selenide is an organophosphorus compound with the formula (C6H5)3PSe. It is a white solid which is soluble in most organic solvents. The compound is used in the preparation of other selenium compounds and is itself prepared by the reaction of triphenylphosphine with potassium selenocyanate. Single crystals have been isolated with both monoclin…
