1,2-Bond shift isomerization of oxiranes on copper-graphimet
Abstract
2,2,3,3-Tetramethyloxirane (1) undergoes isomerization on copper intercalated graphite (graphimet) to t-butyl methyl ketone (4)via a 1,2-methyl migration and to 2,3-dimethylbut-3-en-2-ol (5)via a 1,3-hydrogen shift, as well as deoxygenation and dehydration products.
