       RP/I2 reaction  Bookmark   

Here's a process I've seen a couple times in various experimental organic chemistry books (including the one I've had for 25 years):  the reduction of benzilic acid with red phosphorus and iodine.  Also see US patent 3084099.

Synthesis of benzilic acid: https://www.rhodium.ws/chemistry/dimenoxadol.html (at the bottom of the page). What do you need it for?
