A green procedure for the diazotization-iodination of aromatic amines under aqueous, strong-acid-free conditions

A convenient and mild one-pot method for the synthesis of iodoarenes in high yields by the sequential diazotization-iodination of aromatic amines with a reusable polymeric diazotization agent in the presence of p-toluenesulfonic acid at room temperature in water was developed. The method is general and is the greenest alternative of the known diazotization-iodination methods. The method is also effective for the preparation of 1H-benzo[d][1,2,3]triazole and benzo[d][1,2,3]thiadiazole. Georg Thieme Verlag Stuttgart ? New York.

Preparation method of 3,5-diphenylbromobenzene

The invention belongs to the field of organic synthesis and provides a novel method of synthesizing 3,5-diphenylbromobenzene. 2,4,6-Tribromoaniline is used as a start material subjected to diazotization iodination and Grignard reaction to obtain 3,5-diphenylbromobenzene. Compared with traditional synthetic processes, the novel process has simple synthetic steps; the materials selected are easy toattain and low in price; the two reaction steps are easy to implement; the product yield is high; 3,5-diphenylbromobenzene is easy to industrially produce.

N-PHENYL TRISCARBAZOLE

The present invention relates to a novel triscarbazole compound having substituent on N-phenyl, which can be represented by Formula (I). wherein R1 is selected from the group consisting of hydrogen, halogen or alkyl or alkoxy group having 1 to 20 carbon atoms wherein at least one hydrogen atom is optionally replaced by halogen; RA, RB, RC, RD and RE are any of substituents other than hydrogen wherein at least two of R1 and RA may further form a fused ring; and i, j, k, l and m are same or different at each occurrence and represent an integer from 0 to 4, with the proviso that when R1 is hydrogen, i is not 0. By introduction of the substituent on N-phenyl, the device efficiency, stability and lifetime can be increased while maintaining the solubility. These compounds can be used in various organic devices such as organic light emitting diodes, photovoltaic cells or organic semiconductor devices.
