An Effective Route to a C-Phosphorylated Pyridazinone via use of Ph2Li. Synthesis and Quantum-chemical Calculations

Tyryshkin N.; Polezhaeva N.; Prosvirkin A.; Sahibullina V.; Chmutova G. (1997)

Reaction of Ph2PLi and Ph2PH with 4,5-dichloro-2-phenylpyridazin-3-one was studied. A bis-phosphorylated pyridazinone, 4,5-bis(diphenylphosphino)-2-phenylpyridazin-3-one was prepared. Quantum-chemical calculations were ...
New Reaction of 3,4-Dichloro-5-hydroxy-2(5H)-furanone with Trimethylsilylphosphites

Polezhaeva N.; Loginova I.; Ovechkina E.; Galkin V.; Sahibullina V.; Cherkasov R. (1996)

The new reaction path of the phosphorylation of 3,4-dichloro-5-hydroxy-2(5H)-furanone with trimethylsilylphosphite is found. It is established that the reaction involves two reaction centres to give 4- and 5-phosphorylation ...
Peculiarities of dehydrohalogenation of phosphonium salts under the action of BuLi. Synthesis and X-ray and quantum-chemical studies of a new stable ylide

Polezhaeva N.; Prosvirkin A.; Sahibullina V.; Litvinov I.; Gubaidullin A.; Naumov V.; Chmutova G. (1999)

The reaction of tributyl(5-hydroxy-3-oxo-2-phenylpyridazin-4-yl)phosphonium chloride with butyllithium involves dehydrohalogenation to form the corresponding ylide. The structure of the latter is studied by X-ray diffraction ...
Phosphorylation of 3,4-dichloro-5-hydroxy-2(5H)-furanone with tributylphosphine

Polezhaeva N.; Volodina Y.; Kalinina I.; Sahibullina V.; Chmutova G.; Galkin V.; Cherkasov R. (2002)

The reaction of 3,4-dichloro-5-hydroxy-2(5H)-furanone with 2 mol of tributylphosphine involves substitution of both chlorine atoms to form an unstable diphosphonium salt. The latter undergoes partial hydrolysis with cleavage ...
Synthesis of the first C-phosphorylated pyrrol-2(5H)-one. Quantum chemical calculations of the pyrrol-2(5H)one structures

Polezhaeva N.; Sahibullina V.; Kostyunina T.; Prosvirkin A.; Tyryshkin H.; Chmutova G. (1996)

A new approach to the synthesis of the first C-phosphorylated pyrrol-2(5H)-one is developed. Direct reaction of 3,4-dichloropyrrol-2(5H)-one with P-nucleophiles fails to give the desired compounds. This fact was explained ...
