Compounds bearing ortho-oriented dialkylamino and boryl groups can serve as efficient reagents to trap difluorocarbene leading to zwitterionic ammonium borates featuring N-CF2-B fragments. The reagents are shelf-stable and can be used as mechanistic probes for reactions proceeding via difluorocarbene.
1,2-Bis(4-pyridyl)ethylene undergoes a photoinitiated [2+2] cross-cycloaddition reaction with allyl groups of allylmalonate in pores of a 3D metal–organic framework (MOF) [Zn2(H2O)2(Amal)2(bpe)] to produce a 3D MOF with a new topology.
