Conclusions
When diethyl ether is placed in contact with certain noble metals of group VIII, dehydrocyclization of the ether occurs, forming tetrahydrofuran and its decomposition products. The observed reaction is analogous to C5-dehydrocyclization of hydrocarbons and cyclization of secondary amines to pyrrolidine.
