In this study, a mechanochemical adaptation of the McMurry coupling reaction was developed to synthesize ethylenes using Zn/TiCl4/Et3N as reagents.
This perspective summarizes recent advances in synthetic strategies and insights into ring contraction effects on ring-contracted porphyrin-related macrocycles, including subporphyrins, triphyrins(2.1.1), and calix[3]pyrroles.
A simple and practical decarboxylative carbonyl olefination is described. This procedure explores the application of α-halo NHPI redox-active esters in organic chemistry.
A sequential dehydrogenation reaction of activated diarylmethane derivatives mediated by copper(II) pivalate was developed, for preparation of electron-deficient tetraphenylethene (TPE) derivatives.
Chiral helicenes can be built by catalytic asymmetric transformation of pre-existing, easily accessible biaryl precursors using conceptually novel strategies such as olefin metathesis, alkyne hydroarylation, C–X coupling, and C–H functionalization.
