The novel high-silica zeolite SSZ-42 was synthesized and characterized by X-ray diffraction, scanning electron micrographs, transmission electron micrographs, argon and hydrocarbon adsorption, elemental analysis, 13 C MAS NMR, FTIR, and catalytic reactions. The framework topology of SSZ-42 has been
The dynamics of tetrapropylammonium (TPA) cations occluded during the synthesis of a siliceous MFI zeolite were investigated by several 13C high-resolution NMR methods. This work follows and complements a previous 1H broad-line NMR study of this material. The evolution of the 13C cross polarization
Enamines 5 , prepared from heterocycles with a methyl group at a-position in respect to ring nitrogen atom 1 and N,N-dimethylformamide dimethyl acetal ( 3 ) or t-buthoxy-bis(dimethy1amino)methane (4), are transformed with 2-phenyl-5(4H)-oxazolone (1) into the corresponding intermediates 2, which cy
