Sonochemical reactions of lead tetraacetate with 4-substituted styrenes

A good linear free energy relationship was observed between the radical reactivity of the sonochemical reactions of 4-substituted styrenes with lead tetraacetate and the vapor pressure of the styrenes, indicating a probable control of the process by an intra-bubble activation.

Screening of liver acetone powders in the resolution of 1-phenylethanols and 1-phenylpropanols derivatives

Hydrolases from the liver acetone powders (LAPs) of bovine, cat, chicken, turkey, lamb, pig, rabbit, and rat were assessed for the enantioselective hydrolysis of acetates of 1-(4-chlorophenyl)ethanol, 1-(3-bromophenyl)ethanol, 1-(4-chlorophenyl)propanol, 1-(4-bromophenyl)propanol, and 1-(3-bromophenyl)propanol. The enantioselectivity of the hydrolytic reaction was dependent upon the liver hydrolase, substrate, pH of the reaction media, and the cosolvent. The most ester selective LAP was from chicken, and the resulting alcohols had the highest ee (80% to >99%). All of the LAPs tested catalyzed the hydrolysis of 1-(4-chlorophenyl)ethanol, except for lamb LAP.
