Borrowing hydrogen catalysis is an important catalytic concept. Borrowing hydrogen can be seen as an example of Green chemistry . It is based on the intermediate oxidation of an alcohol substrate to the corresponding aldehyde by the catalyst which borrows hydrogen from the substrate the intermediate aldehyde then reacts with e.g. a secondary amine in a condensation reaction to produce e.g. an imine , that is then reduced by the catalyst in the final step to yield e.g. a tertiary amine . ref cite journal doi 10.1002 adsc.200600638 title Borrowing Hydrogen in the Activation of Alcohols year 2007 last1 Hamid first1 Malai Haniti S.
