As the [2Fe]H subsite models of [FeFe]-hydrogenases, a series PNP-chelated and -bridged diiron dithiolate complexes 1a–f 2a–f together with three related monophosphine 3a–c were prepared by selective substitutions all-carbonyl complex Fe2(μ-pdt)(CO)6 (A, pdt = SCH2CH2CH2S) aminodiphosphines (Ph2P)2NR (denoted as PNP) under different reaction conditions. The first UV irradiation toluene solutions A PNP ligands (PNP (Ph2P)2NR; R (CH2)3Me, (CH2)3NMe2, (CH2)3Si(OEt)3, C6H5, C6H4OMe-p,...
As a further exploration of the asymmetrically substituted diiron models for active site [FeFe]-hydrogenases, two new types small bite-angle aminodiphosphine [(Ph2P)2NR; denoted as PNP in this study]-chelated N-phenyl-aza- and ethanedithioate complexes Fe2(μ-xdt)(CO)4{κ2-(Ph2P)2NR} (1a–1e) (2a–2e), respectively, were successfully synthesized by carbonyl substitution reactions all-carbonyl Fe2(μ-xdt)(CO)6 (xdt = SCH2N(Ph)CH2S (adtNPh) SCH2CH2S (edt)) with (PNP (Ph2P)2NR, R CMe3, CH2CHMe2,...
Diiron dithiolate complexes have received special attention because of their structural similarity to the active site [FeFe]-hydrogenases, which are most efficient and fastest catalysts for generation dihydrogen in nature. Recently, we established a novel way prepare phosphine-substituted diiron aza- oxadithiolate complexes. Reaction Fe2(μ-SCH2OH)2(CO)6 several phosphine ligands L (L = PPh3, PPh2(2-C5H4N), P(C6H4-4-CH3)3) affords intermediate Fe2(μ-SCH2OH)2(CO)5L, while situ reacts with...
Three new propanedithiolate-type iron–sulfur complexes containing tris(aromatic)phosphine ligands, [{(μ-SCH2)2CH2}Fe2(CO)5L] (L = P(PhOMe-p)3, 1; P(PhMe-p)3, 2; P(PhF-p)3, 3), have been prepared through carbonyl substitution in the presence of Me3NO. The 1–3 were characterized by elemental analysis, IR, 1H, 13C{1H}, and 31P{H} NMR spectra. molecular structures unequivocally determined single crystal X-ray diffraction, which coordinated to Fe resides an apical position pseudo-square-pyramidal...
Designing molecular catalysts to enhance hydrogen evolution activity presents both great significance and challenges. In hydrogenases, the redox group (i.e., [4Fe4S] subcluster) near catalytic active center [2Fe2S] plays...
ABSTRACT A novel phosphorous‐nitrogen containing intumescent flame retardant, toluidine spirocyclic pentaerythritol bisphosphonate (TSPB), was synthesized and characterized by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR). Flame retardant rigid polyurethane foams (TSPB‐RPUF) were prepared using TSPB. The retardancy of TSPB on (RPUF) investigated the limiting oxygen index (LOI), vertical burning test, thermogravimetric analysis (TGA), scanning electron...
In this paper, zinc phytate was prepared and used as a synergist in intumescent flame-retarded polypropylene composites. The results showed that the composites with 17 wt% flame retardant 2 have limiting oxygen index 29.2 achieve UL-94 V-0 rating. Moreover, peak heat release rate of decreases from 374 to 275 kW/m2. Real-time Fourier-transform infrared spectroscopy delays emission carbon dioxide indicating slows degradation which regulates suitability flame-retardant system polypropylene.
