Additives Promote Divergent Reactivity in Photolytic Deoxygenation and Lactonization Reactions of Cobalt Alkoxycarbonyls. [PDF]

European J Org Chem
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.

Insecticidal Activity of Trichilia hirta L. (Sapindales: Meliaceae) Extracts Against Spodoptera frugiperda (Lepidoptera: Noctuidae) Larvae and the Identification of Bioactive Compounds. [PDF]

Chem Biodivers
Fruits of Trichilia hirta were extracted and fractionated according to solvent polarity. The resulting partitions were screened for insecticidal activity by evaluating larval mortality and weight after 7 and 14 days. LC‐MS analysis of the most active fraction enabled the annotation of secondary metabolites potentially associated with the observed ...
