Multiple rearrangements of 1-methoxyfluorenylidene to 1-phenanthrenol
摘要:
Flash vacuum pyrolysis of 1-methoxy-9-diazofluorene (1) yielded 1-phenanthrenol (2). Experiments with H-2- and 13-C-labelled 1 revealed that the source of C10 of 2 is the methoxy carbon of 1, whereas the likely source of C9 of 2 is the diazo-substituted carbon of 1.
