Synthesis and Characterization of Stable Phosphorus Carbabetaines
Phosphorus 1,3- and 1,4-carbabetaines with ?P(+)?C?C(?)? and ?P(+)?C?C?C(?)? structures, respectively, in which the carbanion moiety was significantly stabilized by two trifluoromethylsulfonyl groups, have been synthesized and characterized. Analysis of their X-ray crystal structures revealed that any attractive interactions between the anionic and cationic moieties were negligibly weak. This result was corroborated by using natural bond orbital (NBO) and Bader?s quantum theory of atoms in molecules (QTAIM) models. In contrast, performing the same analysis of a known 1,3-carbabetaine equivalent, which can be drawn as a ?P(+)?C?C=C?O(?)? resonance structure, revealed pronounced charge-transfer interactions between the anionic and cationic moieties.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of Tris(2,4-dimethylphenyl)phosphine, you can also check out more blogs about49676-42-8
