ИСТИНА

We have found that some reactions can proceed only when a cymantrenyl fragment is introduced into the substrate molecule. It was shown that the substituent migration and transalkylation reactions in the triazole ring proceed during the alkylation of 1-cymatrenalkyltriazoles due to an increase in the stability of the carbocation, which is associated with a partial redistribution of the charge on the manganese atom.Monitoring of photolysis of O-alkylated quinazolin-4-one 1 showed that unexpected N-substituted tricarbonyl complex 2 and chelate complex 3 were formed. during the reaction.It should be noted that the reaction rate is affected by the rate of CO removal from the “solvent cage” after breaking bond Mn - CO in the starting compound 1.
