Process for preparing derivatives of (halo)amino-1,3,5-triazines by carbonylation |
March 6, 2001 |
| Provided is a process for preparing carbonylated derivatives of amino- and haloamino-1,3,5-triazines by contacting the 1,3,5-triazine, carbon monoxide and a metal catalyst system containing a metal promoter for promoting carbonylation, at a temperature carbon monoxide pressure and le |

Process for making alkyl arsine compounds |
May 16, 1995 |
| Alkyl arsines are made by a reaction of gaseous arsine and the corresponding gaseous olefin in contact with at least one Bronsted acid catalyst. Products produced thereby are mono- and di-substituted arsines, e.g. alkyl and di-alkyl arsines, which contain substantially no metallic or |
