How is Dibenzo[b,d]furan-2-ol (CAS: 86-77-1) typically synthesized?

Dibenzo[b,d]furan-2-ol (CAS: 86-77-1) can be synthesized through the reduction of dibenzo[b,d]furan using hydrogen gas in the presence of a palladium catalyst. Another method involves the hydroxylation of dibenzo[b,d]furan using oxygen and a suitable metal catalyst like molybdenum or tungsten. The yields are typically good, but the selectivity can vary based on the reaction conditions.
