N-Hexyl phenyl ketone

C6H5-C = CHC4Hg-n from a-diazoketones. Ethereal methyllithium added dropwise at 0 to a soln. of di-n-butyl-(l-phenyl-l-hexenyloxy)borane prepared from diazoacetophenone and tri-n-butylborane in tetrahydrofuran, the ice bath removed, stirred 1 hr. at room temp., methyl iodide added, and stirring continued 1.5 hrs. 2-hexyl phenyl ketone. Y 69%. Via vinyloxyboranes, a,a- and ,/5-dialkylated ketones can be obtained in good yield from a-diazoketones and methyl vinyl ketone respectively. F. e. s. D. J. Pasto and P. W. Wojtkowski, J. Org. Chem. 36, 1790 (1971). 

Methyl-n-hexyl-keton- [3-catboxy-phenyl hydrazon] 16 1 205. 

Treatment of 2 -anilinofluorans with ketones such as acetone or 2-butanone in hydrochloric acid in the presence of iron(III) chloride gives 4,4 -alkylidenebis(A-fluoran-2-ylaniline)s. Thus, 2 -anilino-6 -(A-cyclohexyl-/V-methylainino)-3 -methylfluoran, (86) is treated with acetone in hydrochloric acid in the presence of iron(III) chloride to give 2,2-bis(4-[6 -(N-cy c 1 o hexyl-Ar-methy 1 amino)-3 -methylfluoran-2 -ylamino]phenyl (propane (87)60 (Eq. 9). 

Ketones of the type RCOCHRj, where R represents methyl, ethyl, isopropyl, -butyl, 7 -hexyl, or phenyl, and R represents ethyl, n-propyl, -butyl, or phenyl, have been prepared by a series of reactions similar to that used in the preparation of aldehydes (method 167). ...
