Monoterpenes such as alpha-pinene, beta-pinene, limonene and isolimonene undergo smooth hydroalkoxylation in the presence of 20 mol % of FeCl3 under mild reaction conditions to produce a wide range of the corresponding ethers in excellent yields and with high selectivity.

This report discloses the deallylation of O- and N-allyl functional groups by using a combination of a Ni-H precatalyst and excess Brønsted acid. Key steps are the isomerization of the O- or N-allyl group through Ni-catalyzed double-bond migration followed by Brønsted acid induced O/N–C bond hydrolysis. A variety of functional groups are tolerated in this protocol, highlighting its synthetic value
