AN INFRARED SPECTROSCOPIC STUDY OF THE FORMALDEHYDE COMPLEXES OF DIMETHYL ETHER AND METHANOL IN SOLID NITROGEN

Ir spectra of the formaldehyde complexes of methanol and dimethyl ether in solid nitrogen at 20 K are reported.Dimethyl ether forms a non hydrogen bonded complex, analogous to a previously studied dimethyl sulfide-formaldehyde complex.Methanol forms a hydrogen bonded complex with formaldehyde and in addition appears to form another complex probably with a structure similar to that of the dimethyl ether-formaldehyde complex.

Reactions and products revealed by NMR spectra of deuterated dimethylsulfoxide with iodomethane in neutral and basic media

Reactions occurring within each one of two mixtures, a mixture of deuterated dimethylsulfoxide, DMSO-d6, with CH3I (system I) and another mixture of DMSO-d6 with CH3I, NaOH and water (system II), were monitored by 1D and 2D nuclear magnetic resonance (1H, 13C, heteronuclear multiple quantum correlation, heteronuclear multiple bond correlation and diffusion-ordered NMR spectroscopy). The analysis of the spectra as a function of reaction time revealed the formation of methoxy-bis(trideuteromethyl)sulfonium iodide, 3; the precipitation of hexadeuterated trimethyloxosulfonium, 2a; a methyl exchange between DMSO-d6 and 2a to produce trideuterated dimethylsulfoxide, DMSO-d3, 4, and nona-deuterated trimethyloxosulfonium iodide, 2b; and the production of small quantities of methanol, 5, trideuterated dimethylsulfide, 6, and dimethyl ether, 7, in both systems. Only system II precipitated deuterated [Na4(DMSO-dx)15][(I3)3I], 1a, a green solid with metallic shine that corresponds to an isotopomer of 1, which is produced by the self-assembly of DMSO and CH3I in the presence of NaOH and water.

Experimental evidence from H/D exchange studies for the failure of direct C-C coupling mechanisms in the methanol-to-olefin process catalyzed by HSAPO-34

(Chemical Equation Presented) Pool view preferred: In agreement with recent theoretical work, a new line of experimental evidence was obtained in support of the controversial claim that direct mechanisms do not couple methanol to ethylene in the catalyzed methanol-to-olefin process. The results preclude carbene routes and oxonium ylide mechanisms, among others (see picture), in favor of the hydrocarbon pool mechanism.
