Base-mediated denitrative C3-alkylation of quinoxaline derivatives We have developed a novel base-mediated method for the selective C3-alkylation of quinoxalin-2(1H)-one and N-protected quinoxalin-2(1H)-one using inexpensive, unactivated nitroalkanes. This approach tolarated wide range of functional groups and supports for synthesis of various bioactive compouns . Gram-scale reactions demonstrate the scalability of the method. The proposed mechanism was validated by control experiments.

Depolymerization of Waste Polyethylene to Linear Alkenes via Sequential Dehydrogenation and Metathesis Polyethylene (PE) is the most abundantly sourced plastic and significant efforts are needed for its end-of-life management. The deconstruction of PE is an uphill task and requires the breaking of highly stable C-C bonds. Here we demonstrate that PE can be deconstructed to value-added dodecene, along with other long-chain alkenes.
