The cover of this week’s OBC features work from Min Shi et al. at Shanghai Institute of Organic Chemistry and 
Texas Tech University, who have used chiral zinc(II)–imidazoline–phosphine complexes in a novel catalytic system for the asymmetric Mannich-type difluorination of hydrazones with difluoroenoxysilanes.
