Ethyleneurea fused with a norbornane ring was prepared. Acid-catalyzed polycondensation of the urea with paraformaldehyde yielded a new six-membered hemicucurbituril derivative. The presence of hemicucurbiturils containing from four to eight monomer units were also detected.

Influences of Phenyl Rings on NHC Ligands with Bicyclic Architectures
properties that make them bulky but accessible. In this study, we synthesized a novel type of NHC ligand that possesses a bicyclo[2.2.1]heptane architecture, and we compared five derivatives using copper-catalyzed allylic arylations with aryl Grignard reagents. The regioselectivity of the substitution obviously indicates that a phenyl ring over an active site has a characteristic effect on the resultant
