Convenient methods for the synthesis of functionalized organophosphorus compounds containing carbonyl groups as well as di- or trialkoxymethyl fragments attached to phosphorus, and their derivatives, starting from the available derivatives of trivalent phosphorus acids, are proposed, and some properties of the new functionalized organophosphorus compounds are presented. So, the alkylation and acylation

mass is growing rapidly, particularly in the United States. Glycerol3-phosphate acyltransferase (GPAT) catalyzes the rate-limiting step of glycerolipid biosynthesis, the acylation of glycerol3-phosphate with saturated long-chain acyl-CoAs. In an effort to produce small molecule inhibitors of this enzyme, a series of benzoic and phosphonicacids was designed and synthesized. In vitro testing of this series
members of series when investigating the stereochemistry of heterocycles substituted at the phosphorus. The examination of 1H, 13C and 31P NMR spectra has shown that substitution of hydrogen at the phosphorus by axial halogen, alkyl, alkoxy and amido-groups is accompanied by shielding of 4,6-C atoms and deshielding of 4,6-axial protons; introduction of an axial Me group into γ-position to the P-H fragment
2-H-1,3,2-二恶英,二硫杂,二氮杂和氧杂氮杂膦酰基已通过还原相应的磷酰氯而制得。已经研究了这些化合物的光谱和化学性质。当研究在磷处取代的杂环的立体化学时,这些化合物被认为是系列的初始成员。对1 H,13 C和31 P NMR谱的研究表明,磷被轴向卤素,烷基,烷氧基和酰胺基取代时,会同时屏蔽4,6-C原子和对4,6进行脱屏蔽-轴向质子;将轴向Me基团引入PH片段的γ位会导致磷核共振发生30–40 ppm的高场偏移。

The paramagnetic adducts between a variety of phosphinyl, phosphonyl or thiophosphonyl radicals and thiobenzophenone, 9,H-xanthen-9-thione, 9, H-thiaxanthen-9-thione, 9, H-selenaxanthen-9-thione and di-tert-butyl thioketone have been generated and studied by means of ESR spectroscopy. Attention has been focused on the variations of(31P) with the nature of the ligands L in the attacking PLn radicals
