Introduction

5,9-Dibromo-7,7-diphenyl-7H-benzo[c]fluorene (DBDPBF) is an organic compound with an aromatic core structure consisting of a benzofluorene ring with two bromine substituents. It is used in the manufacture of various products such as pharmaceuticals, pesticides, and dyes.

Synthesis

DBDPBF is synthesized by a two-step process. In the first step, the reaction of 1-bromoprop-2-ene and phenylmagnesium bromide in tetrahydrofuran (THF) yields the intermediate 2,6-dibromonaphthalene. This intermediate is then reacted with phenylmagnesium bromide in THF to produce DBDPBF.

Properties

DBDPBF has a molecular weight of 364.12 g/mol, a boiling point of 464.2 °C at 101.3 kPa, and a melting point of 165-167 °C. It is a white crystalline solid that is insoluble in water and slightly soluble in organic solvents. It has a characteristic aromatic odor and is stable under normal conditions.

Uses

DBDPBF is used mainly in the manufacture of pharmaceuticals, pesticides, and dyes. It is used as an intermediate in the synthesis of pharmaceuticals such as antifungal, anti-inflammatory, and anticonvulsant drugs. It is also used in the synthesis of certain pesticides and dyes.

Safety

DBDPBF is toxic if inhaled, ingested, or absorbed through the skin. It is an irritant to the eyes and skin and can cause skin sensitization. It should be handled with caution and protective clothing and equipment should be worn when handling this compound.

Conclusion

DBDPBF is a white crystalline solid with an aromatic odor that is used in the manufacture of pharmaceuticals, pesticides, and dyes. It is synthesized through a two-step process and is toxic if ingested, inhaled, or absorbed through the skin. It should be handled with caution and protective clothing should be worn when handling this compound.
