阳离子黄杂环己烯基膦钯烯丙基络合物能有效催化烯丙基醚脱烯丙基化为醇类和伴随的烯丙基胺的形成。平行实验和密度泛函理论计算表明，在以烯丙基醚为ETA(2)配体的16VE络合物中，酸催化对C-O键的断裂起着重要的促进作用。
A cationic xanthene phosphole palladium allyl complex efficiently catalyzes the deallylation of allyl ethers into alcohols and the concomitant formation of allyl amines. Parallel experiments and DFT calculations show that acidic catalysis plays a significant role in promoting the cleavage of the C-O bond in a 16 VE complex featuring an allyl ether as eta(2)-ligand.
