1311951 Aromatic substitution of olefines PRB SA 9 April 1970 [10 April 1969 13 Nov 1969 31 March 1970] 16906/70 Heading C2C A process for the arylation of an olefin comprises reacting an aryldiazonium salt with an olefin in an unbuffered medium in the presence of a catalytic amount of a copper halide in the presence of an alkanoic acid at a temperature of from 0‹ to 40‹ C. The invention also comprises 1 - chloro - 3 - methyl - 4 - (6 - chloroo - tolyl) - but - 2 - ene, 1,2,3 - trichloro- 4 - (2,4,5 - trichlorophenyl) - but - 2 - ene, 1 - (2,6 - dichlorophenyl) - 4 - chlorobut - 2 - ene, 1 - chloro - 3 - methyl - 4 - (2,6 - dichlorophenyl)- but - 2 - ene, 2,3 - dichloro - 4 - (2 - fluorophenyl)- n - butane, 1 - chloro - 3 - methyl - 4 - (A) - but - 2 - ene, 1,2,3 - trichloro - 4 - (A) - but - 2 - ene, 1,2 - epoxy - 3 - chloro - 4 - (A) - butane, where A = 2 - chlorophenyl, 1,2 - dichloro - 3 - (4 - chlorophenyl)- n - butane, 1 - chloro - 4 - (3,4 - dichlorophenyl)- but-2-ene and the following compounds where B = 3-chloro-o-tolyl:α-bromo-#-(B)-propionitrile,α- chloro -α- methyl - (B) - propionitrile, methylα,α- dichloro - # - (B) - propionate, # - chloro -γ- (B) - butyro - nitrile, 2 - chloro- 3 - (B) - propanol,α- chloro - # - (B) - propionaldehyde,α- chloro - # - (B) - n - butyraldehyde, 1 - chloro - 2 - (B) - ethyl acetate, 1- chloro - 1 - phenyl - (B) - ethane, 1-chloro- 3 - methyl - 4 - (B) - but - 2 - ene, 2 - chloro- 3 - (B) - propyl formate, 3 - [2 - chloro - 3 - (B)- propoxy] - propanol, 1 - chloro - 4 - (B) - but- 2 - ene, 3 - chloro - 3 - methyl - 4 - (B) - butan- 2 - one, 1,2 - dichloro - 2 - methyl - 3 - (B)- propane, 1 - ethoxy - 1 - chloro - 2 - (B) - ethane andα- chloro -α- methyl - # - (B) - propionaldehyde.
