2-Methyl-5-tert-butylcyclohexanone

The aryl and enol triflates 306 and 307 couple with Me3Al, Et3Al and BU3AI [136], The enol phosphate 309, derived from ketone 308, is displaced with methyl group of Me3Al using Pd catalyst in dichloroethane. Based on this reaction, 4-tert-butylcyclohexanone (308) is converted to 2-methyl-5-tert-butylcyclohexanone (311) via 310 [137],... 

Iodine fluoride is a more versatile reagent than molecular fluorine in geminal fluorination of other hydrazones and related compounds under milder reaction conditions [55] Substrates fluorinated include hydrazones of simple cyclic or steroidal ketones (e g, 4 tert butylcyclohexanone, 70%, 3 cholestanone, 70%), W methyl and A/N dimethylhydrazones [R2C=NNH(CH3) 70%, R2C=NNC(CH3)2, 50%], semicarbazones (R2C=NNHCONH2, 25-50%), and 2,4-dinitrophenylhy-drazones [R2C==NNH-C6H3-2,4(N02)2, 25-50%]...
