2-Aminobiphenyl

2-Aminobiphenyl (2-APB) is an organic compound with the formula C6H5C6H4NH2. It is an amine derivative of biphenyl. It is a colorless solid, although aged samples can appear colored even black.[1] Palladacycles obtained from 2-aminobiphenyl are popular catalysts for cross-coupling.[2]
