We report the synthesis of cyclic cobaltocenium olefins (cationic cobaltocenophane or ansa-cobaltocenium). This is prepared by ring-closing metathesis (RCM) diallyl cobaltocenium, which isomerizes into two different dienes. The isomerization terminal alkene at higher temperature results in thermodynamically more stable internal alkene, supported computational calculation. RCM these isomers prod...

This account critically surveys the field of side-chain transition metal-containing polymers as prepared by controlled living ring-opening metathesis polymerization (ROMP) of the respective metal-incorporating monomers. Ferrocene- and other metallocene-modified polymers, macromolecules including metal-carbonyl complexes, polymers tethering early or late transition metal complexes, etc. are here...

Ring-opening metathesis polymerization (ROMP) of norbornene (NB) and its derivatives N-adamantyl-exoendo-norbornene-5,6-dicarboximide (AdNDI) and N-cyclohexyl-exo-endo-norbornene-5,6-dicarboximide (CyNDI) in the presence of cis-1,4-dichloro-2-butene (2a) and cis-1,2-dichloro-ethylene (2b) as chain transfer agents (CTAs) using a [1,3-bis(2,4,6-trimethylphenyl)-4,5-dihydroimidazolilydene] (PCy3)C...

In living ring-opening metathesis polymerization (ROMP), a transition-metal-carbene complex polymerizes ring-strained olefins with very good control of the molecular weight of the resulting polymers. Because one molecule of the initiator is required for each polymer chain, however, this type of polymerization is expensive for widespread use. We have now designed a chain-transfer agent (CTA) cap...

Group communication protocols are used in fault-tolerant systems to maintain strong replica consistency. The FaultTolerant Multicast Protocol (FTMP) described here is a group communication protocol specifically designed for the Common Object Request Broker Architecture (CORBA). FTMP operates over IP Multicast, and consists of the Reliable Multicast Protocol (RMP) that provides reliable source-o...
