The ratios of isomers formed in the free-radical methylation of pyridine and 3- and 4-picoline have been determined and the results compared with the corresponding phenylations. The results support the concept that methyl radicals are more nucleophilic than phenyl radicals.

AbstractThe reactions of (Ph3Sn)2O with PhMePOCl and with Ph2POCl lead to Ph3SnO2PMePh and Ph(SnO2PPh2, respectively. Ph3SnO2PMe2 has been prepared from the reaction of (Ph3Sn)2O and Me2PO2H in toluene. The IR and Raman spectra of Ph3SnO2PMe2, Ph3(SnO2PMePh and Ph3SnO2PPh2 are found to be consistent with polymeric structures with pentacoordinated tin atoms. The EI mass spectra indicate that the principal fragmentation processes of Ph3SnO2PRR′ (RR′ = Me2, MePh, Ph2) appear to occur by loss of phenyl radicals from tin and by elimination of the entire diorganophosphinate group.
