Bis(5H-dibenzo[a,d]cyclohepten-5-yl)amine
Bis(5H-dibenzo[a,d]cyclohepten-5-yl)amine (CAS 57705-01-8) is a specialised organic ligand precursor with the molecular formula C30H23N and a molar mass of 397.51 g/mol. Commonly abbreviated trop2NH, it is a secondary amine bearing two 5H-dibenzo[a,d]cycloheptenyl (dibenzosuberenyl) groups, each carrying a reactive olefinic bridge. It is used principally in organometallic and coordination chemistry as a building block for amido and diolefin "trop" ligands in transition-metal catalysis research.

Organometallic ligand precursor
Serves as the parent secondary amine (trop2NH) for preparing amido-type "trop" ligands. Deprotonation of the N-H gives an amido nitrogen that coordinates to transition metals such as rhodium and iridium.
Coordination and catalysis research
The two pendant dibenzocycloheptenyl olefins can bind a metal centre alongside the amido nitrogen, supporting the study of homogeneous catalysts. It is supplied for laboratory and research-scale synthesis.
Chemical synthesis building block
Acts as a structurally rigid, polycyclic amine scaffold in multi-step organic and organometallic synthesis. Its defined geometry makes it useful where a hindered, sterically demanding nitrogen donor is required.
Reference and method development
The high-assay material is appropriate as a characterised intermediate for method development, ligand screening and exploratory coordination studies.
