概要： We have recently discovered that Ti imidos (L_n Ti=NR) can catalyze oxidative nitrene transfer reactions from diazenes via a Ti^II /Ti^IV redox couple, and are using this new mode of reactivity to develop a large suite of practical synthetic methods. In this talk, our latest synthetic and mechanistic discoveries related to Ti nitrene transfer catalysis will be discussed, including new synthetic methods for the modular, selective construction of pyrroles^1) via [2+2+1] cycloaddition of alkynes with Ti nitrenes and alkynes, as well as new methods for catalytic oxidative carboamination of unsaturated organics by Ti nitrenes.^2)
