Dual reactivity of 1,2-disubstituted dihydro-N-heteroaromatic systems. 2. Mechanism of the dehydrogenation of N-acyldihydroquinolines and isoquinolines with 2,2,6,6-tetramethyl-1-oxopiperidinium perchlorate
The mechanism of the heterolytic dehydrogenation of various N-acyl derivatives of α-substituted 1,2-dihydroquinolines and isoquinolines with 2,2,6,6-tetramethyl-1-oxopiperidinium perchlorate was investigated.
