Please could anyone enlighten me on the use of monopotassium phosphate in the decarboxylation of phenylglycidic acid salts from the Darzen condensation of benzaldehydes with chloroacetic/2-chloropropionic acid esters...
Is this advantageous over decarboxylation with acids such as HCl/AcOH, a la Barium?
Is it applicable for phenylacetaldehydes and P2Ps, or just phenylacetaldehydes?
The potassium salt of the phenylglycidic acid was used in all the cases of KH2PO4 decarboxylation i have seen; is there a reason for this (instead of the sodium salt)?
Would KH2PO4 be incompatible for decarboxylation of epoxy acid salts formed from benzaldehydes containing more sensitive functional groups, e.g. iodo, methylenedioxy, etc?
Thankx in advance,
