The reduction of the carbonyl group in acylated trifluoroethyl alkanesulfonates follows the Felkin-Ahn selectivity, and the so-formed diastereomeric β-hydroxysulfonyl intermediates undergo syn- and anti-fragmentation, depending on the reaction conditions. In effect, isomeric E- and Z-alkenes are formed in a stereodivergent manner, which mimics the mechanistic manifold of the Peterson olefination.

Matrix presented Dehydrogenation and subsequent transimination of primary amines offer a new pathway for C-H bond activation, ortho-alkylation, and C-C bond activation to afford a variety of ketones in the reaction of 1-alkene by a cocatalyt system of Rh(I) and 2-amino-3-picoline.
Arylation of α-substituted acrylates in ionic liquids catalyzed by a Pd-benzothiazole carbene complex

A Pd-catalyst with benzothiazole carbene as ligands allows, in tetrabutylammonium bromide melt as solvent, very fast and efficient reactions of bromoaromatics with 3-hydroxy-2-methylenealkanoates to give β-arylketones.
Catalytic activation of C-H and C-C bonds of allylamines via olefin isomerization by transition metal complexes

(matrix presented) The metal-catalyzed reaction of olefins with allylamines bearing coordination sites (2-pyridyl groups) was studied. With Ru3(CO)12 as catalyst, activation of C-H bonds led to the formation of ketimines that were hydrolyzed to give asymmetric ketones. With [(C8H14)2RhCl]2, both C-H and C-C bonds were activated and symmetric ketones were formed on hydrolysis. The reaction involves double bond migration of the allylamine to form an aldimine.
Oxidation of sec-Alcohols to the Corresponding Ketones by Corynebacterium equi
Ohta, Hiromichi,Fujiwara, Hidenori,Tsuchihashi, Gen-ichi
, p. 1509 - 1516 (2007/10/02)
Corinebacterium equi IFO 3730 was found to oxidize a wide variety of sec-alcohols, including alkanols, substituted alkanols, alkenols and cyclic alcohols, in moderate to high yields.Among them, the sec-alcohols which have longer carbon chains were oxidized more smoothly than those with smaller numbers of carbon.Although both enantiomers of unsymmetrically disubstituted carbinols were oxidized, the S form of 2-dodecanol was converted to the corresponding ketone a little faster than the other enantiomer.

Corynebacterium equi IFO 3730, which had previously been demonstrated to be capable of assimilating 1-hexadecene, also showed good growth on 1-hexadecen-11-ol (1a).The corresponding ketone, 1-hexadecen-11-one (2a) was isolated as the product from the broth.This microorganism-mediated oxidation has been revealed to have a wide applicability, and a variety of sec-alcohols were oxidized to the corresponding ketones in good yields on incubation with the bacterium growh on 1-hexadecene as a sole source of carbon.
