Usage

General Description

CHLORO(BIS-PENTAFLUOROETHYL)PHOSPHINE is a chemical compound with the formula C2ClF10P. It is a colorless, flammable gas with a pungent odor. It is primarily used as a reagent in organic synthesis, particularly in the synthesis of organophosphorus compounds. It is also used as a ligand in coordination chemistry, where it can form complexes with transition metals. CHLORO(BIS-PENTAFLUOROETHYL)PHOSPHINE is highly reactive due to the presence of the pentafluoroethyl groups, and it should be handled with care in a well-ventilated area.

Chlorobis(pentafluoroethyl)phosphane: Improved synthesis and molecular structure in the gas phase

(C2F5)2PCl is now accessible through a significantly improved synthesis protocol starting from the technical product (C2F5)3PF2. (C2F 5)3PF2 was reduced in the first step with NaBH4 in a solvent-free reaction at 120 °C. The product, P(C 2F5)3, was treated with an excess of an aqueous sodium hydroxide solution to afford the corresponding phosphinite salt Na +(C2F5)2PO- selectively under liberation of pentafluoroethane. Subsequent chlorination with PhPCl 4 resulted in the selective formation of (C2F 5)2PCl, which was isolated by fractional condensation in an overall yield of 66 %. The gas electron diffraction (GED) pattern for (C 2F5)2PCl was recorded and found to be described by a two-conformer model. A quantum chemical investigation of the potential-energy surface revealed the possible existence of many low-energy conformers, each with a number of low-frequency vibrational modes and therefore large-amplitude motions. The conformer calculated to be most stable was also found to be most abundant by GED and comprised 61(5) % of the total. The molecular structure parameters determined by GED were in good agreement with those calculated at the MP2/TZVPP level of theory; the only significant difference was a discrepancy of about 3° in the C-P-C angle, which, for the lowest-energy conformer, was refined to 98.2(4)° and was calculated to be 94.9°.
