REACTIONS OF DIHYDROPYRIDINES WITH BENZYNE
Reactions of 1 ,Zdihydropyridines (la-c) and 1,4-dihydropyridines (2a-c) in the presence of benzyne (3) under thermal conditions, and in the case of (2c) under photochemical conditions, have been investigated. Benzyne acts as an oxidizing agent to convert dihydropyridine (la) and (2a) to the corresponding pyridine (4) or adds as a dienophile to (lb-c).

متن کاملPhotochemical dehydrogenation of 3,4-dihydro-2-pyridones.
Photochemical dehydrogenation of various substituted 3,4-dihydro-2-pyridones was achieved in a very efficient way by employing 10-15 mol% of photo-induced electron transfer sensitizers like 9-cyanoanthracene, 9-cyanophenanthrene and 1-cyanonaphthalene in presence of molecular oxygen, for the first time.
متن کاملBENZYNE AS AN INTERMEDlATE IN NUCLEO - PHILIC AROMATIC SUBSTITUTION REACTIONS
IT sometimes happens in organic chemistry that a large body of related fact accumulates which seemingly cannot be rationalized on the basis of the currently available theoretical concepts. In such circumstances, substantial clarification may often be achieved by an approach which is novel only in application .to the system at band. The pieces of the puzzle may then fall into place and experimen...
