Hydrolysis of 1,1,3,3-tetrakis(dimethylamino)-1l5,3l5-diphosphete

Hydrolysis of 1,1,3,3-tetrakis(dimethylamino)-1l5,3l5-diphosphete. Fluck, Ekkehard; Spahn, Manfred; Heckmann, Gernot (Gmelin-Inst. Anorg. Chem. 103678-18-8 and 2511-17-3 are also occured in this study., Max-Planck-Ges., Frankfurt/Main W-6000/90, Germany). Z. Anorg. Allg. Chem., 601, 65-72 (German) 1991. CODEN: ZAACAB. ISSN: 0044-2313. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Hydrolysis of title compd. I in dioxane yields (Me2N)2PMe:CHP(O)(NMe2)2 in the first step. In the second step Me2NP(O)MeCH2P(O)(NMe2)2 is the main product of hydrolysis. In addn., small amts. of MeP(O)(NMe2)2 are formed. The mechanism is discussed. .

Effect of the structure of phosphoryl-containing compounds on their ability to solvate lithium and potassium cations based on results of measuring the H- function of solutions of tert-butoxides in tert-butyl alcohol

Effect of the structure of phosphoryl-containing compounds on their ability to solvate lithium and potassium cations based on results of measuring the H- function of solutions of tert-butoxides in tert-butyl alcohol. Osipenko, N. G.; Petrov, E. S.; Tsvetkov, E. N.; Ranneva, Yu. I.; Shatenshtein, A. I. (Fiz.-Khim. Inst. im. Karpova, Moscow, USSR). Zh. Obshch. Khim., 46(12), 2647-54 (Russian) 1976. CODEN: ZOKHA4. DOCUMENT TYPE: Journal CA Section: 68 (Phase Equilibriums, Chemical Equilibriums, and Solutions) Substituent effects on solvation of Li+ and K+ by phosphoryl compds. were studied in tert-BuOH solns. contg. tert-BuOM (M = Li,K) by detg. the H- function; the dielec. const. of some liq. compds. was also detd. Solvating capacity increases with decreasing shielding of the P:O group (the principal solvation site) and with introduction of addnl. solvation centers by adding alkoxymethyl or polyoxyalkyl groups. The strength of the polydentate effect for K+ solvation depends on the distance of the O-contg. substituent groups from the P:O group. Liq. phosphine oxides contg. 1 Me or 2 polyoxyalkyl groups have greater solvating capacities than the well-known dipolar aprotic solvents such as DMSO, hexametapol, etc. The H- function of tert-BuOK solns. (0. 61748-77-4 and 2511-17-3 which are cas registry numbers of substances are two of reagents here.14M) is 2.2 log units .gtoreq. H- of tert-BuOLi solns. (0.14M); this difference is reduced or eliminated by adding P:O-contg. solvating compds. (3.4 mol %). .
