A Sygmatropic Hydrogen Shift Induced by High Vibrational Overtone Excitation: The Isomerization of 2-Methylcyclopentadiene

Laser excitation of high CH stretching overtone transitions has been used to induce the isomerization of 2-methylcyclopentadiene to 1-methylcyclopentadiene.The reaction is a sigmatropic hydrogen shift and therefore the reaction coordinate involves significant hydrogen atom motion.This provides a reasonable experimental test for the possibility that overtone excitation of CH stretching motions may lead to enhanced unimolecular reaction rates if there is strong coupling between the reaction coordinate and the nuclear motions which are excited by photon absorption.Values of the unimolecular reaction rate constant, k(E), have been deduced from photochemical quantum yields for excitation of the methylenic, methyl, and olefinic fourth CH stretching overtone transitions of 2-methylcyclopentadiene.No rate enhancement is observed for excitation of the methylenic transition compared to the methyl or olefinic trannsitions.The values of k(E) scale only with total energy and are in reasonable agreement with values calculated from RRKM theory.

Synthesis of isoprene from formaldehyde and isobutene over phosphate catalysts

Vapor phase Prins condensation of isobutene with formaldehyde has been studied over boron (BP), aluminum (AlP), titanium (TiP), zirconium (ZrP) and niobium (NbP) phosphates. The catalysts were characterized by elemental analysis, X-ray diffraction, low-te

Removal of alcohols and water from a methylcyclopentadiene recycle stream in a process for the synthesis of methylcyclopentadienyl manganese tricarbonyl

During the process of synthesis of methylcyclopentadienyl manganese tricarbonyl (MMT), a key raw material methylcyclopentadiene (MCP) is used. The MCP component may be recycled for subsequent reaction processes. The recycle stream of MCP is washed with water and, optionally, passed over a molecular sieve bed to remove the contaminants protic side products from the MCP recycled stream.
