Direct nucleophilic substitution reactions between 5-aryl-1,9-dihalodipyrromethenes and pyrroles were developed.By controlling the reaction temperature,both
Over the past decade,interest in the field of porous organic polymers(POPs),which have strong covalent linkages,light-weight elements,tunable pore parameter
The CoⅡ(ttp)catalyzed carbon-carbon bond transfer hydrogenation of [2.2]paracyclophane(PCP)with DMF was achieved.Mechanistic investigation suggested that t
