p-benzoquinone addition mechanism?

[Rhodium]

p-Benzoquinone reacts with trialkylboranes to give 2,5-dihydroxyalkylbenzenes, with sodium thiosulfate to give 2,5-dihydroxyphenylthiosulfate etc.

What is the mechanism behind this? What other stuff can generally be added to p-benzoquinone? I would very much like to have some kind of review article on addition to benzoquinone, besides the obvious diels-alder pericyclic addition. Anyone here who could help me with a reference of some sort?

I'm not sure if this:

is what you are looking for. I hope you can read it.

Thank you, exactly what I'm looking for. What reference is it taken from, Chemishe Berichte?

I don't want to be picky when I got all this from you, but the pages 608, 616 and 620 is missing, and there are doublets of 622, 623 and 625 in their places...

The documents are from Houben-Weyl: Methoden der organischen Chemie (

http://www.indiana.edu/~cheminfo/h-wguide.html

). You might find it in your library. I'll scan the missing pages and put them on the web.
