Conclusions
-
1.
The salts of the Group II metals cause the carbonylation of piperidine and diethylamine at 200–250° and a CO pressure of 50–200 atm predominantly to the corresponding formyl derivative in up to 82% yield when based on amine taken for reaction.
-
2.
The chlorides are the most effective, the activity of which decreases in the order: CaCl2 > SrCl2 > MgCl2 > BaCl2.
