Diethyl allyl phosphate, allyl diethyl phosphate (DEAP)
Diethyl allyl phosphate is hydrogen acceptor, that can for example be used in Pd-catalyzed oxidations.
The use of allyl-palladium catalysis enables a one-step α,β-dehydrogenation of ketones via their zinc enolates. The optimized protocol utilizes commercially available Zn(TMP)2 as base and diethyl allyl phosphate as oxidant, operates under salt-free conditions, and tolerates a diverse scope of cycloalkanones.
