Error in diagram
For the first example, Wurtz coupling of benzyl chloride, are we missing a methylene group from the product?--Rifleman 82 04:52, 11 November 2007 (UTC)

What is this Phase N terminology?
"This phase 0 material must be handled in an inert atmosphere. Heating phase 0 at 150 °C (302 °F) takes it to phase I. When this material is exposed to dry oxygen the reducing power is not affected. At further heating to 400 °C (752 °F) phase II can be handled safely in an ambient environment." I am not familiar with phase 0, phase I, phase II or similar terminology in respect to materials or reactions (only w.r.t. project management or clinical drug trials). I searched on wikipedia and found nothing that seemed applicable. What does it mean and/or where can someone look for further information? Is this Materials Science or Chemistry terminology? Or...?
