, few catalysts are capable of preventing overoxidation of methane to carbon dioxide (CO2). Several alternative strategies for activating methane have
been reported, including multistep oxyfunctionalization with Periana catalysts,(1, 2) borylation,(3) and electrophilic carbene insertion,(4, 5) but
all have fallen short of producing methanol directly.
iron-(9, 10) and copper-(11-13) exchanged zeolites have emerged as a promising class of materials capable of selectively oxidizing CH4 into
surface-bound methoxy species by hosting active sites akin to those found in CH4 monooxygenases. Despite their potential, these materials have only
been shown to oxidize CH4 to CH3OH stepwise and stoichiometrically with molecular oxygen (O2)(11, 14, 15) or catalytically with hydrogen peroxide,(16)
making the process prohibitively expensive

If only methane wasn't so stubborn
Are all alkanes this stubborn

In my universities lab, I'm going to be working on a direct oxidation of hexane to adipic acid in a few months, but its a crazy synthesis involving an
2 aminohexane intermediate that reacts with hexachloroplatinate to get terminal oxidation of the alkane. So, yes, with the amount of work it took to
get this synthesis to give a selective oxidation, I agree that alkanes are the most annoying and stubborn groups to do reactions on.

Should be easy to get a desired reaction with methanol by comparison with hexane as it only has one carbon to pick from.should simplify things
