Enol acetal synthesis through carbenoid C-H insertion into tetrahydrofuran catalyzed by CpRu complexes
Intermolecular C-O instead of C-C bond formation is achieved with [CpRu(CH3CN)3][PF6] and diimine ligands as catalysts of the decomposition of α-diazo-β-ketoesters in THF leading to original products of 1,3C-H insertion (s
