how to convert methane to cubane
Answers
Answer:
Pyrolysis reactions of cubane and methylcubane were studied in a micro-flow tube reactor from room
temperature to 1000 K. The composition of the flow tube eluent was probed by chemical ionization, followed
by analysis in a tandem, guided-beam mass spectrometer. It was found that cubane and methylcubane have
nearly identical breakdown temperature dependence, suggesting that methyl functionalization has minimal
effect on the stability of cubane cage bonds. There is, however, a substantial effect of the methyl group on
product branching, resulting in more stable isomers at intermediate temperatures, and a propensity to eliminate
fragments containing the methyl group at high temperatures. Ab initio calculations performed to aid
interpretation are discussed, along with possible mechanisms.Pyrolysis reactions of cubane and methylcubane were studied in a micro-flow tube reactor from room
