Additives Promote Divergent Reactivity in Photolytic Deoxygenation and Lactonization Reactions of Cobalt Alkoxycarbonyls

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
We report a carbonylation‐homolysis process to access acyl radicals that can undergo decarboxylation or cyclization onto tethered alkenes. In both cases, ligands and additives are shown to influence the outcome to give saturated or unsaturated products, in some cases with isomerization of the initial products.

Residual Life Assessment of Oil‐Immersed Insulating Paper by FTIR Feature Interpretability Evolution

open access: yesHigh Voltage, EarlyView.
ABSTRACT The ageing of insulating paper escalates the peril of insulation failure in oil‐impregnated‐paper power equipment. Consequently, the real‐time monitoring and non‐destructive assessment of insulating paper condition assume paramount significance.
