How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

A molybdenum(IV) complex, trans-MoCl 4 (CH 3 CN) 2 was used as a pre-catalyst in the presence of PTA (1,3,5-triaza-7-phosphaadamantane) in hydrosilylation of 1-heptyne and 1,6-heptadiyne using a tertiary hydrosilane, Ph 2 MeSiH. The silylated products formed were characterized by Gas Chromatography (GC), Nuclear Magnetic Resonance (NMR) Spectroscop...
A number of platinum(II) and palladium(II) coordination complexes bearing PTA and DAPTA ligands have been synthesized. These complexes have been characterized by means of a variety of techniques including NMR and IR spectroscopy, Mass spectrometry, elemental analysis, and X-ray crystallography. The catalytic activity of these complexes was investig...
Two platinum(II) bidentate PTA complexes, cis,cis-[PtMe 2 (µ-P,P) 2 (µ-R) 2 PtMe 2 ] 4+ 4Br-[P = PTA, R = C 6 H 4 (m-CH 2-) 2 and C 6 H 3 CH 3 (2,4-CH 2-) 2 ] were synthesized via ligand substitution method by the reactions of 1,1'-[1,3-phenylenebis(methylene)]bis-[3,5-diaza-1-azonia-7-phosphatricyclo(220.127.116.11)]decane dibromide and [1,3-tolylenebis(...
A novel phosphine, P-isopropylacetonate N-methyl-1,3,5-triaza-7-phosphaadamantane, has been synthesized as a triflate salt from the reaction of 1,3,5-triaza-7-phosphaadamantane with methyl triflate in dry acetone in the presence of minimal amount of D2O and triflic acid. The compound was characterized by NMR spectroscopy, IR spectroscopy, and mass...
Pd(II) dinuclear phosphines, in general, have been found to be more unstable at room temperatures than corresponding Pt(II) complexes. What is the main reason behind this? I encountered this issue while synthesizing bridging PTA complexes.
