摘要:
THIS INVENTION RELATES TO IMPROVE METHODS OF CARBONYLATING, DIMERIZING, HYDROGENATING AND/OR ISOMERIZING VARIOUS UNSATURATED ORGANIC COMPOUNDS WHICH COMPRISES PERFORMING THE DESIRED CHEMICAL REACTION IN THE PRESENCE OF A SMALL BUT EFFECTIVE AMOUNT OF AN ORGANOMETALLIC CATALYTIC AGENT OF THE FORMULA:
1-(Y-M-),2-(Z-A-),(R)N-BENZENE
WHEREIN N IS AN INTEGER FROM 0 TO 4; EACH R IS ALKYL, ARYL, HYDROXY, ALKOXY, ARYLOXY, NITRO, HALO, OR A SECONDARY ALKYL OR ARYLAMINO; M IS RUTHENIUM, PLATINUM, OSMIUM, PALLADIUM, IRIDIUM, OR RHOADIUM: Y IS HALIDE, NITRATE, ACETATE, THIOCYANATE OR CYANIDE: A IS -CR''=N-. (WHEREIN R'' IS HYDROGEN, ALKYL OR ARYL),-NH-NH-,
-N(=O)=N-
OR -N=N; AND Z IS ALKYL, ARYL, R-SUBSTITUTED ARYL, (WHEREIN R IS AS DEFINED HEREINABOVE), ALKARYL, ALKOXY, ARYLOXY, HYDROXY, ALKYL AMINO, DIALKYL AMINO, ARYL AMINO OR DIARYLAMINO.
摘要:
A process for the preparation of unsaturated acyl halides by carbonylating vinylic halides in the presence of a Group VIII noble metal catalyst. Acryloyl chloride, for example, is formed by reacting vinyl chloride with carbon monoxide in the presence of a palladium metal catalyst at a temperature of from about 25* to 300* C., and a pressure from about 5 to 500 atmospheres.
