Abstract Efficient and high-yield functionalization of graphene represents a significant challenge in graphene chemistry, particularly due to low graphene reactivity. We report on a facile and effective method for the covalent grafting of hydrocarbon chains onto graphene surface leading to high-degree of functionalization. The alkylated, alkenylated and arylated graphenes were achieved by reaction of fluorographene with Grignard reagents at ambient temperature. The reaction resulted to covalently, homogeneously and double-sided hydrocarbon-derivatized graphenes with a high degree of functionalization ranging from 5.5 to 11.2%, which were thermally stable to 200 °C. The results suggest that the efficacy of the reaction depends on the nucleophilicity of hydrocarbon anions formed from the Grignard reagents
