| titleOfInvention | Aryl magnesium chloride complexes |
| abstract | The invention comprises aryl magnesium chloride complexes of formula: <PICT:0776993/IV(b)/1> where Q is tetramethylene or pentamethylene oxide which may be substituted by a substituted or unsubstituted alkyl radical containing no group which is reactive under the reaction conditions, n is an indeterminate number of the order of 1 to 3, R1 . . . R5 each represents hydrogen, chlorine, an alkyl, aryl, alkoxy or aryloxy which may be substituted by any group which is not reactive under the reaction conditions and wherein any two or more adjacent hydrocarbon groups may be linked or condensed to form an aromatic ring. The compound Q may be tetrahydrofuran tetrahydropyran and 2-methyl tetrahydrofuran. Aryl chlorides which may be used include phenyl, tolyl, biphenyl (xenyl), terphenyl, naphthyl, anthracyl, chlorophenyl, phenanthryl, polychlorophenyl, polychlorobiphenyl, xylyl, 2-(or 3,4,5,6,7 or 8) phenylnaphthyl, anisyl, phenetyl, pyrenyl, cadalenyl, perylenyl, acenaphthalenyl, chrysenyl, picenyl, chlorotolyl and tetralinyl. The aryl chloride may be dissolved in the compound Q and the mixture added to the magnesium. Ethyl bromide and an iodine crystal with or without ether may be added as a reaction activator. In an example a flask is charged with magnesium turnings and purged with nitrogen. Tetrahydrofuran and an initiator consisting of ethyl bromide and an iodine crystal are added, followed by a solution of chlorobenzene in tetrahydrofuran. Heating is applied to complete the reaction. Other examples describe the preparation of tetrahydrofuran complexes of p - chlorophenyl -, 3 : 4 - dichlorophenyl-, 2 : 4 : 5 - trichlorophenyl -, 2 : 3 : 4 : 5 : 6 - pentachlorophenyl -, chlorotolyl -, o - tolyl - p - tolyl-, m - tolyl -, and 2 - ethoxy - phenyl - magnesium chlorides. |
