Room-temperature reduction of sulfur hexafluoride with metal phosphides
Huchenski, Blake S. N.,Speed, Alexander W. H.
, p. 7128 - 7131 (2021/07/28)
Upon treatment with sulfur hexafluoride, alkali metal diphenyl or dicyclohexyl phosphides are oxidized within seconds to tetraphenyl or tetracyclohexyl diphosphines. When bulky di-tert-butylphosphide is employed, fluorophosphine intermediates are detected. This is the first reported reaction of sulfur hexafluoride with metal phosphides, and a rare example of reactivity of sulfur hexafluoride at ambient temperature. This journal is
METHOD FOR PRODUCING NITRILE COMPOUNDS FROM ETHYLENICALLY UNSATURATED COMPOUNDS
-
Paragraph 0079-0080, (2014/09/16)
The present invention relates to a method for the hydrocyanation of organic ethylenically unsaturated compounds including at least one nitrile function. The invention specifically relates to a method for the hydrocyanation of a hydrocarbon compound including at least one ethylenic unsaturation by a reaction with hydrogen cyanide in a liquid medium and in the presence of a catalyst including a metal element selected from the transition metals and an organophosphorous ligand, the organophosphorous gaud including a compound of general formula (I), where R1 and R2, which are identical or different, are a linear or branched alkyl radical having 1-12 carbon atoms, which can include heteroatoms, or an optionally substituted aromatic or cycloaliphatic radical that can include heteroatoms, wherein the covalent bond between P and R1, and that between P and R2, are P—C bonds.

Ligand maps lead to treasure! The activity of complexes of fluorophosphines (R2PF) in catalytic hydroformylation and hydrocyanation is predicted from a ligand map. However, the instability of R2PF to disproportionation is well-documented. Examples of R2PF ligands (see scheme) are described that are stabilized to such an extent that they can be used in catalysis and are shown to be highly effective.

The reaction of lithiated precursors with PCl2F led to a number of monofluorophosphines, including the known di-tert-butylmonofluorophosphine, 1.Bis(phenylethinyl)monofluorophosphine (2) was accessible only via this route (the classical method of synthesi

The geometric structures of tert-butyldifluorophosphine, di-tert-butylfluorophosphine, and tri-tert-butylphosphine have been determined in the gas phase by electron diffraction. Successive substitution of fluorine atoms by tert-butyl groups results in the lengthening of both P-F and P-C bond distances. The P-F bond lengths increase from 1.589 (3) ? in ButPF2 to 1.619 (7) ? in But2PF. The P-C bond lengths increase even more strongly from 1.822 (12) ? in ButPF2 to 1.859 (6) A in But2PF to 1.919 (5) ? in But3P. The bond angles at the phosphorus atom follow the opposite trend. The CPF angle decreases from 99.0 (0.6)° in ButPF2 to 96.0 (2.0)° in But2PF, and the CPC angle decreases from 113.8 (1.9)° in But2PF to 109.9 (0.7)° in But3P. The geometric parameters and the configuration of the tert-butyl groups are given in the paper. The electron diffraction results are compared with results obtained by CNDO/2 calculations. The effect of steric strain on the geometry caused by the bulky tert-butyl groups is discussed.
