Structure and dynamics of phosphorus(V)-stabilized carbanions: A comparison of theoretical, crystallographic, and solution structures
Cramer, Christopher J.,Denmark, Scott E.,Miller, Paula C.,Dorow, Roberta L.,Swiss, Kevin A.,Wilson, Scott R.
, p. 2437 - 2447 (1994)
The rotational coordinates about the P-C bond in four different phosphorus(V)-substituted methyl anions have been studied in detail at the HF/3-21G(*) level, with stationary points characterized at levels equivalent to MP3/6-31+G*//HF/6-31+G*. The locatio
Palladium-catalyzed cross-coupling reactions of organocopper derivatives of methylphosphonic esters and amides with aryl and hetaryl iodides
Lukashev,Tarasenko,Beletskaya
, p. 172 - 178 (2007/10/03)
Copper derivatives of methylphosphonic amides are sufficiently stable thermally and can be used in palladium-catalyzed arylation reactions resulting in synthesis of previously unknown aryl- and hetaryl-methylphosphonic tetramethyldiamides in high yields.
Nucleophilic substitution reactions of benzyl- and diphenylmethylphosphonamidic chlorides with amines: Competition between the usual SN2(P) mechanism and elimination-addition with an alkylideneoxophosphorane (phosphene) intermediate
Harger, Martin J. P.
, p. 41 - 47 (2007/10/03)
The substitution reaction of PhCH2P(O)(NMe2)Cl with Me2NH or Et2NH in CHCI3 is very sensitive to the bulk of the nucleophile (≥ 200 times slower with Et2NH), affords only the product derive
Cross-coupling reactions of organocopper derivatives of methylphosphonic acid esters and amides with aryl and hetaryl iodides catalyzed by palladium
Lukashev,Tarasenko,Beletskaya
, p. 1150 - 1156 (2007/10/03)
Organocopper derivatives of methylphosphonic acid esters and amides were demonstrated to be sufficiently thermally stable to be applied to Pd-catalyzed arylation reactions resulting in high yield of previously unknown tetramethyldiamides of aryl and hetarylmethylphosphonium acids.
Low-Temperature Reduction of Benzyl Halides with Magnesium in a Hexamethylphosphoramide Matrix
Egorov,Anisimov
, p. 68 - 73 (2007/10/03)
Low-temperature reaction of ground-state (1S) magnesium with benzyl halides in a hexamethylphosphoramide (HMPA) matrix follows one-electron transfer mechanism. HMPA coordinates to magnesium even at 77 K, thus stabilizing radical ion pairs and causing the reaction to proceed in part along the radical ion pathway. The formation of radical ion pairs is a reversible process which is accompanied by reaction of benzyl halides with the radical ion pair Mg+-HMPA+ according to the dissociative electron capture mechanism.
