Selective oxidation of aliphatic C-H bonds in alkylphenols by a chemomimetic biocatalytic system.
Selective oxidation of aliphatic C-H bonds in alkylphenols serves significant roles not only in generation of functionalized intermediates that can be used to synthesize diverse downstream chemical products, but also in biological degradation of these environmentally hazardous compounds. Chemo-, regio-, and stereoselectivity; controllability; and environmental impact represent the major challen...
متن کاملUltrasound-assisted synthesis of aliphatic acid esters at room temperature.
This work describes the ultrasound-assisted synthesis of saturated aliphatic esters from synthetic aliphatic acids and either methanol or ethanol. The products were isolated in good yields after short reaction times under mild conditions.
متن کاملThe origin of the generalized anomeric effect: possibility of CH/n and CH/pi hydrogen bonds.
Ab initio MO calculations were carried out at the MP4/6-311++G(3df,3pd)//MP2/6-311++G(3df,3pd) level to investigate the conformational Gibbs energy of a series of methyl ethers CH(3)O-CH(2)-X (X=OH, OCH(3), F, Cl, Br, CN, C triple bond CH, C(6)H(5), CHO). It was found that the Gibbs energy of the gauche conformers is lower in every case than that of the corresponding anti conformers. In the mor...
متن کامل6 Analysis of H – AHn and CH 3 – AHn bonds
Along the series of H–AHn bonds, with AHn = CH3, NH2, OH, and F, the bond dissociation energies show a steady increase as can be expected from the increasing difference in electronegativity along this series. However, in the same series for CH3– AHn the bond strength first decreases from CH3–CH3 to CH3–NH2 and only thereafter increases again along CH3–NH2, CH3–OH and CH3–F. To understand the or...
متن کامل7 Activation of H – AHn and CH 3 – AHn bonds
We have studied the palladium oxidative insertion reactions into a series of model bonds across the second period, that is, the H–AHn and CH3–AHn bonds, where AHn = CH3, NH2, OH, and F. We investigate what effect this series of increasingly polar bonds has on their intrinsic barriers upon activation by palladium. Our activation strain analyses show nicely how the observed trends are strongly in...
