Stable endoperoxide of 4,5,6,8,16-pentamethyl[2.2]metacyclophane; structural analysis and deoxygenation
Abstract
Photooxygenation of 4,5,6,8,16-pentamethyl[2.2]metacyclophane 6 gives [2.2]metacyclophane endoperoxide 7; its X-ray crystallographic analysis and stability in the thermal deoxygenation reaction are reported.
