Preparation and photoisomerization of 2-phosphaethenylbenzenes having more than one phosphorus-carbon double bond

Phosphaethenes having more than one phosphorus-carbon double bond on a benzene ring were prepared. The E/Z photoisomerization reactions of these phosphaethenes were studied using 31P NMR spectroscopy. The structure of 1,2-bis[2-(2,4,6-tri-t-but

Synthesis, Structure and Ligand-centred Reduction of an Orthometallated Complex of Palladium containing Two Phosphaalkene Groups

A novel ligand containing two phosphaalkene moieties has been synthesized, which forms a palladium(II) complex whose crystal structure has been determined and whose reduction has been shown, by EPR spectroscopy, to take place on the ligand rather than on

Phosphinidene transfer reactions of the terminal phosphinidene complex Cp2Zr(PC6H2-2,4,6-t-Bu3)(PMe 3)

The terminal zirconium phosphinidene complex Cp2Zr(PR*)(PMe3) (R* = C6H2-2,4,6-t-Bu3) 2 has been synthesized in high yield, and its reactivity has been investigated. The compound Cp2ZrMe(PH

The benzodiphosphaalkene ligand and its PdII and PtII complexes: Their synthesis, structure, and an ESR study of their reduction products

The new diphosphaalkene 1,3-bis[2-(2,4,6-tri-tert-butylphenyl)phosphanediylmethyl]benzene, L, has been synthesized. Due to the presence of two P=C bonds three isomers (EE, EZ, ZZ) were observed by 31P NMR, and the crystal structures of two of them could be determined (EE, ZZ). The electrochemical behavior of L has been studied by cyclic voltametry: a quasi-reversible reduction occurs at -1.89 V/SCE and corresponds to the formation of a radical anion which has been studied by ESR at variable temperature. The experimental 31P and 1H hyperfine constants are consistent with free rotation about the P=C and Cph0sphaalkene-Cbenzene bonds at room temperature and agree with ab initio predictions. One of the isomers of L forms complexes with palladium(II) and platinum(II) ions. The crystal structures show that L is orthometalated and acts as a terdentate ligand by coordinating the metal with each phosphorus atom. These complexes are electrochemically reduced between -0.92 and -1.29 V, and the resulting paramagnetic species are studied by ESR in liquid and frozen solutions. This reduction process was shown to be a ligand-centered process, an appreciable part of the unpaired electron is localized on each of the phosphaalkene carbons (20%) and phosphorus atoms (5%).
