(Chemical Equation Presented) Rare activity from rare earths: Cationic rare-earth hydrides show regio- and stereoselectivity for the polymerization of 1,3-cyclohexadiene (CHD) to afford soluble crystalline cis-1,4-linked poly(CHD) that was previously unavailable. These cationic clusters are made by treating the corresponding neutral complexes with a borate activator (see scheme; Cp′: C5Me4SiMe3).
