Systematic Structural Investigations on Phosphines
نویسندگان
چکیده
This work contributes to the systematic investigation of phosphines. In an attempt to deter mine the nature, shape, volume and direction of the lone pairs at the phosphorus atoms in phosphines, high resolution X-ray structure analyses of triphenylphosphine, tris(p-methoxyphenyl)phosphine, bis(2,4,6-triisopropylphenyl)phosphine, 1,1 -bis(diphenylphosphino)ethene and 4,5,6-triphenyl-4-phosphaspiro[2.4]hept-5-en have been carried out. New valence force field parameters (TRIPOS force field) are presented which were developed on the basis of the molecular structures of the free phosphines. The results of crystal growing experiments using zone melting techniques are summarized.

Carbonylniobium Chemistry, IV [1] Derivatives of ^5-C5H5Nb(CO)4 with Tridentate Phosphines
Recent investigations into the coordinative properties of oligodentate phosphorus ligands towards carbonylvanadium and -niobium complexes in our laboratory have lead to a large body of systematic IR, 31P and metal NMR data, including those on CpV(C0)4 and CpNb(C0)4 derivatives with ditertiary [2-5] and tritertiary phosphines [6, 7]. In this communication, we report on the reaction pattern obser...
متن کاملA direct, modular, and efficient construction of the P-C-P structural motif through coupling of manganese carbyne complexes with phosphines.
Easily available carbyne complexes of manganese were used as a source of carbyne fragments in an unconventional synthesis of backbone-substituted diphosphinomethanes and cyclic P-ylides upon coupling with secondary or tertiary phosphines, respectively, followed by demetalation under mild conditions.

Large water-soluble gold clusters are used for the labelling of biological material to visualize the posi tion of reactive sites by electron microscopy [1]. In most investigations of this type a commercial prod uct was used, for which little chemical information has been published (for review see [9]). Large gold clusters can be prepared using phosphines as lig ands [2, 3] or more easily wit...
متن کاملSupramolecular bulky phosphines comprising 1,3,5-triaza-7-phosphaadamantane and Zn(salphen)s: structural features and application in hydrosilylation catalysis.
The use of the commercially available, bifunctional phosphine 1,3,5-triaza-7-phosphaadamantane (abbreviated as PN3) in conjunction with a series of Zn(salphen) complexes leads to sterically encumbered phosphine ligands as a result of (reversible) coordinative Zn-N interactions. The solid state and solution phase behaviour of these supramolecular ligand systems have been investigated in detail a...
متن کاملA priori assessment of the stereoelectronic profile of phosphines and phosphites.
This research has demonstrated the utility of a rigorously calibrated, molecular mechanics/semiempirical quantum mechanical protocol for developing stereoelectronic (Tolman) maps for phosphine ligands. A computational analysis of alkyl and aryl phosphines in common usage suggests that these ligands are quite similar stereoelectronically. A noticeable gap in the Tolman map for common phosphines ...
