General Description

Phosphine, (phenylmethyl)- is a chemical compound with the formula C7H9P. It is also known as benzylphosphine, and it is a colorless liquid that is highly flammable and reactive. This chemical is often used as a ligand in organometallic chemistry and can act as a stabilizer in the synthesis of metal nanoparticles. It is also used in the production of pharmaceuticals and agricultural chemicals. However, phosphine, (phenylmethyl)- is extremely toxic and exposure to it can cause severe health effects, including respiratory irritation, headaches, and in extreme cases, death. Therefore, it is important to handle this chemical with extreme caution and adhere to strict safety guidelines when working with it.

The Ever-surprising chemistry of boron: Enhanced acidity of phosphine·boranes

The gas-phase acidity of a series of phosphines and their corresponding phosphine·borane derivatives was measured by FT-ICR techniques. BH 3 attachment leads to a substantial increase of the intrinsic acidity of the system (from 80 to 110 kJ mol-1). This acidity-enhancing effect of BH3 is enormous, between 13 and 18 orders of magnitude in terms of ionization constants. This indicates that the enhancement of the acidity of protic acids by Lewis acids usually observed in solution also occurs in the gas phase. High- level DFT calculations reveal that this acidity enhancement is essentially due to stronger stabilization of the anion with respect to the neutral species on BH3 association, due to a stronger electron donor ability of P in the anion and better dispersion of the negative charge in the system when the BH3 group is present. Our study also shows that deprotonation of ClCH2PH2 and ClCH 2PH2·BH3 is followed by chloride departure. For the latter compound deprotonation at the BH3 group is found to be more favorable than PH2 deprotonation, and the subsequent loss of Cl- is kinetically favored with respect to loss of Cl - in a typical SN2 process. Hence, ClCH2PH 2·BH3 is the only phosphine·borane adduct included in this study which behaves as a boron acid rather than as a phosphorus acid.
