A novel pathway for direct conversion of benzylsilanes to phenols by oxidation with Na2S2O8 and oxygen is efficiently developed under mild and neutral conditions. The reaction shows good functional group tolerance to afford phenols in moderate yields. The possible mechanism is proposed based on the isotopic labeling trials.

(Chemical Equation Presented) The Directed ortho Metalation (DoM)/Suzuki-Miyaura cross-coupling strategy is applied for the regiospecific construction of all isomeric monochloro and selected dichloro and trichloro 2,3-dihydroxybiphenyls (DHBs). The combined methodology highlights iterative DoM processes, hindered Suzuki-Miyaura couplings, and advantages in diversity in approaches from commercial starting materials leading to provision of chloro-DHBs as single isomers in high purity and on a gram scale. The syntheis of several PCBs are also reported.

Kinetics and mechanism of aromatic hydroxylation of anisoles by chromic acid has been investigated in 50percent aqueous acetic acid.The reaction followed secod order kinetics, first order each in and at constant and ionic strength.The effect of meta and para substituents on the reaction rates has been studied.The application of LFER to the rates reveals that the site of attack is at the ortho carbon atom but not at the oxygen atom.
