Molecular Models of Early Transition Metal Oxides: Polyoxoanions as Organic Functional Groups, methanol oxidation to give formaldehyde, methacrolein oxidation to give methacrylic acid, propylene oxidation to give acrolein, methane oxidation to give formaldehyde, and propylene metathesis to give ethylene and butene. Due to the difficulty of characterizing surface-bound intermediates, efforts

Homogeneous Models for Mechanisms of Surface Reactions: Propene Ammoxidation,ato W(VI) tert-butyl imido complexes. These compounds exist as an equilibrating mixture of amine-bis(imido) and imido-bis(amido) complexes, the position of this equilibrium being dependent on the electronic nature of the glycolate ligand. Both of the C-N bond-forming reactions proposed in recent stu

Recent Advances in Pillared Clays and Group IV Metal Phosphates,act as pillars to prop open the clay layers thus creating porous structures. Pores larger than those possible in zeolites have been measured in the propped clays. Thus, their potential for the cracking of the heavy gas-oil fraction of petroleum has been examined..The layered compound α-zirconium pho

Reactions of Organometallics with the Surfaces of Zeolites,zeolites. Following a discussion of the chemical and physical factors influencing the interactions of metal complexes and zeolite frameworks, three types of intrazeolitic complexes are described: exchangeable cation-based complexes, occluded (neutral) organometallic species, and framework site-based

Reactions of Organometallic Compounds with Surfaces of Supported and Unsupported Metals,ers with surfaces of supported metals under mild conditions. The reactions lead to the preparation of highly dispersed bimetallic particles, which have homogeneous compositions and nonadditive properties in CO hydrogenation and hydrocarbon conversion.
