Herein, an operationally simple, environmentally benign and effective method for intermolecular radical hydroacylation of unactivated substrates by employing photo-induced hydrogen atom transfer (HAT) initiation is described. The use of commercially available and inexpensive photoinitiators (Ph2CO and NHPI) makes the process attractive. The olefin hydroacylation protocol applies to a wide array of substrates bearing numerous functional groups and many complex structural units. The reaction proves to be scalable (up to 5 g). Different functionalized fatty acids, petrochemicals and naturally occurring alkanes can be synthesized with this protocol. A radical chain mechanism is implicated in the process.

A new mixed-valence SbV/III containing vanadium-substituted polyoxotungstate Na10[{SbV(OH)3} 2{VIV-O(H2O)}2{Sb IIIW9O33}2]·32H2O (1-Na) has been synthesized by routine synthetic reaction and characterized by IR, XPS, elemental analysis. The polyoxoanion [{SbV(OH)3}2{V IVO(H2O)}2{SbIIIW9O33}2]10 (1) consists of two trilacunary species β-B-SbIIIW9O 33 connected by two VIVO(H2O) groups and two SbV(OH)3 units. The cyclic voltammetry and catalytic activity of 1-Na for the oxidation of n-hexadecane under green condition have been measured.

A ruthenium complex, KNa[Ru2(C6H6) 2(CH3COO)6] (Ru-KNa), and its polyoxotungstate derivative, Na6[{Ru(C6H6)}2W 8O28(OH)2]·16H2O (Ru-Na), have been successfully isolated from routine synthetic reactions and characterized by X-ray single-crystal structure analysis, IR spectroscopy and elemental analysis. A remarkable aspect of Ru-KNa is that it has two ligand types, benzene and acetate, and the acetate ligands are connected exclusively by a central Na cation to form a dimeric sandwich-type structure, which is further connected by K cations to construct the 3D structures. Based on complex Ru-KNa, the compound Ru-Na was synthesized, and it consists of two {Ru(C 6H6)} units linked to a [W8O 28(OH)2]10- fragment by three Ru-O(W) bonds to result in an assembly with idealized C2 symmetry in which the polyanions form 3D structures by the connection of Na chains. Subsequently, the compound Ru-Na was anchored on (3-aminopropyl)triethoxysilane (apts) modified SBA-15 to prepare the solid catalysts, which were characterized by powder XRD, N2 adsorption measurements and FTIR spectroscopy. Finally, the catalytic efficiency of Ru-Na was assessed in the oxidation of n-hexadecane with air without any additives and solvents. The results indicated that Ru-Na is a heterogeneous catalyst and exhibits higher catalytic activity than previously reported Ru-containing polyoxotungstates. Copyright

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.
Cycloalkanones. 8. Hypocholesterolemic activity of long chain ketones related to pentadecanone
Wyrick,Hall,Piantadosi,Fenske
, p. 219 - 222 (2007/10/12)
Aliphatic analogs of 2,8 dibenzylcyclooctanone which included C15-C18 ketones have been investigated for hypocholesterolemic activity in rats. The position of the carbonyl group in the chain for maximum activity appears to be the 2 position. 2 Hexadecanone reduced serum cholesterol levels significantly without altering serum triglyceride levels. This drug was not estrogenic at effective doses which is in contrast to the cyclooctanones which possess this activity.
