HCID 11095327Silane, trimethyl[[2-methyl-1-(1-methylethyl)-1-propenyl]oxy]-

Procedure

Reaction between 2,4-dimethyl-3-pentanone (1.2.4.3), trimethylsilyl chloride, and base gave 2,4-dimethyl-3-trimethysilyloxy-2-pentene (1.2.4.4) which was reacted with 1-fluoropyridinium triflate (1.2.4.5) to form 2,4-dimethyl-2-fluoro-3-pentanone (1.2.4.6). This product was reacted with (CH3)3S(O)+I- to form the title compound (1.2.4.2). ##STR31##
