Synthesis of o-isotoluenes, o-quinodimethanes, and benzoenynyl carbodiimides and their cyclizations to polycyclic and heterocyclic compounds
… o-isotoluenes in a single operation. The reaction proceeded through an initial formation of (Z)-diene-allenes, which underwent facile eletrocyclizations to produce o-isotoluenes.;Treatment of allenyldicyclohexylborane with 1-lithio-5,5-pentamethylene-3,4-pentadien-1-yne produced the …

Chemomechanics with a molecular force probe
… that aims at quantitative understanding of reaction dynamics in multiscale phenomena. These are characterized by correlated directional motion at multiple length scales—from molecular to macroscopic. To explain the up to quadrillion-fold variations in reaction rates in multiscale …
