Oxidation of α-Oxo-Oximes to Nitrile Oxides with Hypervalent Iodine Reagents
, 2016 Upon reaction with PhI(OAc)2, α-oxo-aldoximes are oxidized to α-oxo-nitrile oxides, while α-oxo-ketoximes are converted into nitrile oxides via the oxidative cleavage of the carbonyl−imino σ bond.

Advanced Materials, EarlyView.A dual‐additive electrolyte strategy is developed to address the hydrolysis of I+ in the aqueous electrolytes. The steric‐hindrance effect of TES− effectively shields I+ from nucleophilic attacks by hydroxyl groups, facilitating the reversible I−/I0/I+ conversion with four‐electron transfer.

Atmospheric oxidation of nitriles
, 1977 The reports of nitrile formation in actual and simulated auto emissions suggests a potential environmental hazard associated with the wide scale use of catalytic exhaust converters. Specifically, the atmospheric oxidation of nitriles is believed to occur via radical intermediates which can lead to both NO/sub x/ and CO production.

An Advanced Molecularly Imprinted Polymer‐Based Electrochemical Aptasensor for Carbendazim Detection
Advanced Materials Interfaces, EarlyView.A dual‐recognition electrochemical aptasensor that integrates a molecular imprinted polymer (MIP) and an aptamer is developed for the detection of a common pesticide, carbendazim (CBZ). The resulting sensor exhibits enhanced selectivity toward CBZ over structurally similar compounds and achieves a low detection limit of 1.3 nm, demonstrating its ...
