Sodium percarbonate-triflic acid

Adamantanol, the C—H insertion product is formed in a very small amount. 4-Oxahomoadamantane was isolated in a similar good yield (84%) when oxygenation was carried out with sodium percarbonate-triflic acid.210 Two isomeric oxaho-modiamantanes (C—C insertion) and bridgehead diamantanols (C—H insertion) are produced from diamantane.209...
