Process for the preparation of phosphorus derivatives of secondary ammonium salts of penam and cephem compounds |
| abstract |
An improvement in the conversion of penam and cephem compounds to secondary ammonium salts of phosphite amides thereof by reacting as follows: ##STR1## wherein --R, is the non-reacting balance of the penam or cephem compound and ##STR2## ARE NON-REACTING SUBSTITUENTS. Catalytic amounts of H--N< or the hydrogenhalide thereof may be present in the reaction medium. |
