Anilines and ethyl vinyl ether can be used as precursors for a process that is the synthetic equivalent of the α-arylation of acetaldehyde enolate. The reaction manifests a high level of functional group compatibility, allowing the ready preparation of a

An efficient Au(I)-catalyzed synthesis of highly strained and functionalized bicyclo[3.2.0]heptanes is developed. Subsequent couplings with various nucleophiles offer additional structural features/complexity. These one-pot, three-component reactions are proposed to proceed via a key 1,3-dipolar cycloaddition between a Au carbenoid-containing carbonyl ylide

A Pd(II) reagent has been generated at preselected sites on an electrochemically addressable chip and used to effect the oxidation of the neighboring alcohols on the polymer coating the chip's surface. The resulting carbonyls were then used to accomplish site-selective

Soluble methane monooxygenase (sMMO) isolated from Methylococcus capsulatus (Bath) utilizes a carboxylate-bridged diiron center and dioxygen to catalyze the conversion of methane to methanol. Previous studies revealed that a di(mu-oxo)diiron(IV) intermediate termed Q is responsible for the catalytic activity with

A mass spectrometric method has been delineated for the identification of the epoxide functionalities in unknown monofunctional analytes. This method utilizes gas-phase ion/molecule reactions of protonated analytes with neutral trimethyl borate (TMB) followed by collision-activated dissociation (CAD) in an ion
