General description

cis-Cyclooctene undergoes addition reaction with carbon tetrachloride catalyzed by dichlorotris(triphenylphosphine) ruthenium(II) to yield 1-chloro-4-(trichloromethyl) cyclooctane (1,4-adduct). It undergoes epoxidation catalyzed by molybdenum oxide nanoparticles incorporated in a mesoporous silica shell coated on dense silica-coated magnetite nanoparticles.

Application

cis-Cyclooctene has been used to study the alkenes chemisorbed on silicon(100) by scanning tunneling microscopy.

The most fundamental concepts in chemistry are structure, energetics, reactivity and their inter-relationships, which are indispensable for promoting chemistry into a rational science. In this regard, bond energy, the intrinsic determinant directly related to structure and reactivity, should be most

Traditionally, a catalyst functions by direct interaction with reactants. In a new noncontact catalytic system (NCCS), an intermediate produced by one catalytic reaction serves as an intermediary to enable an independent reaction to proceed. An example is the selective oxidation
