Cross-coupling of Grignard reagents with dichloromethane is achieved using iron(III) catalysts. Aryl- and benzylmagnesium bromides show a range of activity toward double C-Cl bond activation resulting in the insertion of methylene fragments between two equivalents of the nucleophilic partner.

The selective conversion of alcohols to alkanes and alkenes is a captivating but extremely difficult process. Herein, we explored the activity of an acridine-derived SNS–Ru pincer complex in the selective conversion of primary alcohols into both long-chain alkenes and alkanes. Both homo- and cross-coupling reactions provide good yields of the desired products with excellent selectivity. Various control
