Spectra and structure of organophosphorus compounds

Spectra and structure of organophosphorus compounds. XXVI. Raman and infrared spectra and normal coordinate calculations for dichloromethyl phosphine, chlorodimethylphosphine, methylphosphinic dichloride, and dimethylphosphinic chloride. Durig, J.In this study， 1111-92-8 and 811-62-1 are also used. R.; Cheng, Mei Shiow; Sullivan, J. F. (Dep. Chem., Univ. South Carolina, Columbia, SC 29208, USA). Indian J. Phys., B, 60B(3), 285-308 (English) 1986. CODEN: IJPBDU. ISSN: 0252-9254. DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Section cross-reference(s): 22 The Raman (50-3500 cm-1) and IR (80-3500 cm-1) spectra of gaseous and solid MePCl2 were measured. The IR spectra of Me2PCl, MeP(O)Cl2 and Me2P(O)Cl in the gaseous and solid states as well as the Raman spectra of the solids were recorded at 80-3500 cm-1. Some of the normal modes of these mols. were reassigned based on IR band contours, Raman depolarization values, and group frequencies. Normal coordinate analyses were carried out for all mols. utilizing modified valence force fields to calc. the frequencies and the potential energy distributions. The extent of the coupling of the skeletal vibrational was ascertained. These results were compared to the corresponding quantities for some similar mols. .

Studies on organophosphorous compounds. IX. C-Phosphorylation of compounds with an active methylene group. Yuan, Chengye; Ding, Yixiang; Long, Haiyan; Li, Shusen (Shanghai Inst. Org. Chem., Acad. Sin., Shanghai, Peop. Rep. China). Huaxue Xuebao, 41(6), 541-50 (Chinese) 1983. CODEN: HHHPA4. ISSN: 0567-7351. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 22 Treating p-RC6H4CH2CN (R = H, Me, OMe, Cl) with Na naphthalenide, followed by (EtO)2P(O)Cl, gave p-RC6H4CH(CN)P(O)(OEt)2 (I). The presence of an electron withdrawing group R decreased the yield. The 31P NMR chem. shifts of I were linearly correlated with the Hammet s consts. for R. 1H NMR spectra indicate that the protons of the ester groups are magnetically nonequiv.There are some commonly used reagents with their cas registry numbers 1111-92-8 and 87361-74-8 in this article. I were alkylated with alkyl halides or condensed with arom. aldehydes by Horner-Wittig type reactions. Treating diketones or ketoesters R1CH2COR2 (R1 = EtO2C, MeCO, PhCO; R2 = Me, Ph) with (EtO)2P(O)Cl gave predominantly Z-R1CH:CR2OP(O)(OEt)2. The effects of metal ions on the reactivity of the enolates was discussed. The regioselectivity of the reaction was discussed in terms of EHMO calcns. .
