The unusualZselectivity of the title reaction is revealed to be determined by the inherent requirements of dynamic preference of pathways that promise theZ-geometry product, rather than the isomerization of theE-productin situ.

Aryl Transfer

We report for the first time a metal-free addition of boronic acids to silylnitronates to afford oxime derivatives through aryl transfer on the carbon nitrogen double bond. A reaction mechanism has been proposed in relation with a DFT study on the key aryl transfer. This arylation process is effective for cycloalkenyl nitro derivatives leading to oximes that may be oxidatively converted into 3-arylisoxazole derivatives.
