Visible-Light-Induced Carbo-2-pyridylation of Electron-Deficient Alkenes with Pyridinium Salts

A simple and practical visible-light-induced carbo-2-pyridylation of electron-deficient alkenes with readily available N-benzoylmethylpyridinium bromides is reported. More than 40 examples are presented and proceed in greater than 80 % yield (on average)

Syntheses of 1-alkyl-2-(substituted-2-pyridyl)benzimidazoles

1-α-Pyridinium acetophenone chloride 2 on reaction with 2-cinnamoylbenzimidazoles 3 followed by alkylation yields1-alkyl-2-(substituted-2-pyridyl) benzimidazoles 5. The latter could also be synthesized by direct reaction of 2 with 1-alkyl-2-cinnamoylbenzimidazoles 6 in accordance with the Kroehnke's pyridine synthesis.

Ba(OH)2 AS CATALYST IN ORGANIC REACTIONS - PART XIX - STRUCTURE-CATALYTIC ACTIVITY RELATIONSHIP IN THE AdN OF SEVERAL YLIDS TO CH=O GROUP, CATALYZED BY ACTIVATED BARIUM HYDROXIDE CATALYST

The reactivity of several products R1R2CH-X(1+), 1, (X=N,P,S), which can produce ylids by reaction with bases, has been tested using the activated barium hydroxide catalysts, C-200.Wittig-Horner, Wittig, Corey-Chaykovsky and Kroehnke type reactions have been analyzed.The pKa of 1, and the structure of active sites control the process.When 1 has a strong acid character, the process takes place - dissolving the solid - in homogeneous phase.When 1, has pKa values 11.7), that control the reaction mechanism and the reactivity of adsorbed ylids.
