Iron-catalyzed cross-couplings of propargylic substrates with Grignard reagents

•Iron has emerged as a “green” and sustainable alternative to the currently widely used precious metals in catalysis.•Advances in iron-catalyzed cross-coupling of Grignard reagents with propargylic substrates are highlighted herein.•Methods for highly selective preparation of propargylic and allene products have been disclosed by several research groups, including examples that demonstrate efficient chirality transfer.
