“…The calculated P=P bond lengths are consistently longer by 0.02 Å, whereas the agreement between computed and observed 31 P NMR data [24] is good. The more computationally intensive model chemistries B3LYP/6-311G** and B3LYP/cc-pVDZ gave geometric data no better than B3LYP/6-31G* (Table S1) thus B3LYP/6-31G* is used here.…”

“…Since formation of the intermediary diphosphene sulfide [9] has not been observed during the sulfurization reaction, monitored by 31P NMR spectroscopy, the isomerization of the diphosphene sulfide seems to be rapid in this captodative diphosphene system.

“…[19] This property is without precedent in iminophosphane chemistry and suggests that the PϭN bond strength is dramatically reduced by ''push-pull'' substitution. Interestingly, the iminophosphane 7 (δ P ϭ 173.1 ppm), which can be obtained by a similar route starting from iPr 2 NPCl 2 and Me 2 NN(SiMe 3 )Li, undergoes dimerization to form trans-[iPr 2 NPNNMe 2 ] 2 (δ P ϭ 74.2 ppm) instead of disproportionation.…”

Abstractσ2λ3‐“Push‐pull” iminophosphanes Arf−P=N−R, bearing an electron‐acceptor substituent at phosphorus [Arf = 2,6‐bis(trifluoromethyl)phenyl] and a donor group at nitrogen (R = tBu, NMe2), have been synthesized and characterized by NMR spectroscopy and X‐ray analysis. Density functional calculations [B3LYP/6‐311G(d,p)] have been carried out on different iminophosphanes: HP=NH (1), ArfP=NH (2), ArfP=NSiMe3 (3), ArfP=NtBu (4), HP=NNMe2 (5) and ArfP=NNMe2 (6) in order to determine the electronic effect of the Arf substituent and the influence of the donor group R on the stability of the monomeric species. A comparison of the theoretical results and UV photoelectron spectroscopy data for the iminophosphanes 4 and 6 is presented. Theoretical and experimental data suggest that for all iminophosphanes under investigation the π‐system of the Arf group is almost orthogonal to the πP=N system, preventing any stabilizing interaction between the πP=N and the π*b1(aryl) orbitals previously observed for the ArfPH− anion. Here, the Arf substituent effect is mainly steric. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
