I was hoping that someone could help me, by clearing up my confusion by providing a somewhat detailed explanation of the role of p-benzoquinone, in terms of the mechanism it uses to regenerate Pd(0) to Pd(II). Typically, CuCl2 is used for this role, so why would one use this benzo, and how does it work? What other roles might p-benzoquinone play? I've heard as a source of oxygen??
Please and thanks,
