Abstract
3,7-Dimethylocta-1,6-diene and 7-methoxy-3,7-dimethyloct-1-ene are catalytically oxidised at the vinyl group by RhCl3–FeCl3 in oxygen to the derived methyl ketones in good yield. An accompanying alkene isomerisation reaction (–CMe·CH:CH2→–CMe:CH·CH3) has been studied. The above octadiene and methoxyoctene are hydroformylated (–CMe·CH:CH2→–CMe·CH2·CH2·CHO) in good yield by [RhH(CO)(PPh3)3], with some accompanying alkene isomerisation.With Tl(NO3)3, 3,7-dimethylocta-1,6-diene reacts at the 6,7-double bond to give a ketone with migration of a methyl group, and at the 1,2-double bond with cyclisation to give cyclopentane derivatives.
