•Use of safer (alkyne, triazole, hydrazone) carbene complex intermediate precursors.•Olefin metathesis in small molecule and polymer synthesis, and Z-selective reactions.•Preparation of novel aromatic ring systems incorporating transition elements.•Complex transformations using gold and platinum carbene-mediated reactions of alkynes.•Design of novel reaction modes to capture transition metal carbenoid intermediates. This is a review of papers published in the year 2017 that focus on the synthesis, reactivity, or properties of compounds containing a carbon-transition metal double or triple bond. Highlights for the year 2017 include: (1) significant advances in the design of new precursors to carbene complex intermediates that serve as safer alternatives to potentially hazardous diazo compounds, (2) continued vast employment of olefin metathesis for the synthesis of complex small molecules and polymers, including many examples of Z-selective and stereoretentive reactions, (3) design of novel transformations employing metallacumulene intermediates, (4) preparation of novel aromatic ring systems incorporating transition elements, and (5) design of reaction processes possibly invoking metal carbene complexes generated from platinum or gold complexes and alkynes.
