Abstract

1319763 Biphenyl and quaterphenyl derivatives and intermediates KODAK Ltd 9 Dec 1970 [9 Sept 1969] 44547/69 Heading C2C [Also in Division G2] 4,4<SP>1</SP>-Di-(5,7-di-t-pentylbenzoxazol 2-yl)biphenyl is prepared as follows: (a) 2,4-di-t-pentylphenol is nitrated with nitric acid to give 2-nitro-4,6- di-t-pentyl phenol which is treated in the presence of aqueous hydroxide with sodium dithionite to give 2-amino-4,6-di-t-pentylphenol; and (b) the amino compound is treated, in the presence of calcium oxide and o-dichlorobenzene, with 4,4<SP>1</SP>-dichlorocarbonylbiphenyl which is made by hydrolysing 4,4<SP>1</SP>-dicyanobiphenyl to give 4,4<SP>1</SP>-dicarboxybiphenyl and treating this with thionyl chloride and dimethyl formamide. 4,4<SP>111</SP>-Di-(5,7-di-t-pentylbenzoxazol-2-yl)p-quaterphenyl is prepared as follows: (a) 4-carboxy-4<SP>1</SP>- iodobiphenyl is prepared from biphenyl via 4-iodobiphenyl and 4-acetyl-4<SP>1</SP>-iodobiphenyl; (b) 4-carboxy-4<SP>1</SP>-iodobiphenyl is converted to 4-carboxy-4<SP>1</SP>-iodobiphenyl by heating with thionyl chloride; (c) the product of (b) is reacted with 2-amino-4,6-di-t-pentylphenol to give 4- iodo - 4<SP>1</SP> - (5,7 - di - t - pentylbenzoxazol - 2 - yl) biphenyl; and (d) the product of (c) is heated with copper powder to give 4,4<SP>111</SP>-di-(5,7-di-tpentylbenzoxazol - 2 - yl)- p - quaterphenyl. 4,4<SP>1</SP>-Dibenzothiazol-2-yl biphenyl is prepared by reacting 4,4<SP>1</SP>-dichlorocarbonylbiphenol with 2- aminothiophenol.
