In the process of establishing an information retrieval system for chemical compounds, which will employ a manual-computer correlation indexing system, we have been using the following nomenclature for boron-phosphorus organic compounds: 1. Basic structures and radicals BHs, borane PH3, phosphine HzP-BH2,phosphinoborane

is named dimethyl-BB-biborophinyl. For ortho-fused ring systems of the linear form the terms borophinoborophine (I), diborophinoborophine (11), etc. are used.
