Taking the first step: A 2‐rhodaoxetane undergoes efficient transmetalation with a variety of functionalized aryl‐ and alkenylboronic acids (see scheme). This process exhibits excellent functional‐group compatibility and constitutes the first step in a proposed catalytic oxidative olefin functionalization.

A 2-rhodaoxetane was found to react with unsaturated electrophiles, such as highly electron-deficient acetylene dicarboxylates, CS2 and various aldehydes, to form a series of six-membered metallacycles. These metallacycles were characterized by 1H, 13C and 2D NMR spectroscopic techniques, as well as HRMS and, for one complex, XRD. In some cases, the insertions were found to be reversible.
