Photochamical Fragmentation of 4-Alkylpyrimidines and 2-Alkylquinolines

Article abstract of DOI:10.1016/S0040-4039(00)88458-0

Hydrogen abstraction and fragmentation occur on acetone-sensitized photolysis of 4-alkylpyrimidines 1a-c with formation of 4-methylpyrimidine (2); the selectivity for primary, secondary, and tertiary hydrogen transfer is considerably greater in 1a-c than in 2-alkylquinolines 7a-c.
