摘要:Methods for the synthesis of polycyclic aromatic hydrocarbons and synthesis platforms for performing such syntheses are provided. Methods and platforms are provided that allow for the synthesis of aza-polycyclic aromatic hydrocarbons by an expedient ring assembly. Methods and platforms allow for a modular approach to synthesis that provide multiple new C—C bonds in sequential pericyclic reactions, thus giving access to compounds with multiple axes of substitution.

摘要:The invention relates to processes for the synthesis of aryl or alkene borates which comprises reacting: (i) an olefinic compound having a halogen or halogen-like substituent in a vinylic substitution position, or (ii) an aromatic ring having a halogen or halogen-like substituent in a ring substitution position, with a disubstituted monohydroborane in the presence of a Group 8-11 metal catalyst. The invention also relates to the use of these borates in coupling reactions. The invention further relates to certain disubstituted monohydroboranes and aryl or alkene borates.
