Kozhevnikov // Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 2001. - Vol. 50, № 11. - P2236-2238 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Iminium salts derived from aromatic aldehydes react with -chlorocarbanions via two different pathways: reaction with secondary carbanion of halomethyl sulfones proceeds as the Knoevenagel condensation, while tertiary -chlorocarbanions gave products of vicarious nucleophilic substitution of hydrogen in parent aldehydes \\\\Expert2\\nbo\\Russian Chemical Bulletin\\2001, 50 (11), 2236.pdf |
