摘要：

The H2PO2-NH4+.H2O/Pd-C system acts as an unusally powerful reducing agent, which is able to reduce cyclooctene to cyclooctane, DELTA9,10-octalin to decalins, alpha- and beta-pinenes to pinanes at room temperature in high yield without the formation of byproducts. This system selectively reduces each of these compounds or partly (alkynes to alkenes), depending on the competition between the transfer hydrogenation to give alkanes and the protonolysis to give hydrogen gas on the palladium catalyst.
