However, the mighty substance doth dissolveth well in acetone, a cosolvent commonly employed in our craft when water alone will not suffice. I have found the sodium salt, it comes cheaply granulated. Perhaps for the reaction of phenylalanine to benzyl cyanide, it would indeed be better employed. I suggest following the literature procedure first however, before innovating, especially when yields are already good. A good point nonetheless. Boogie, lovely! In awe! So cool, the colors--like real chemistry should look! A childs chemistry set! So, tell me-orange = Ph-CH(CN)COCH3 ? blue/green = Ph-CH(CONH2)COCH3, Ph-CH(COOH)COCH3 ? and then decarboxylated into clear P2P?
