General description
N,O-Bis(trimethylsilyl)hydroxylamine on reaction with 9-chloro-9-borafluorene yields 10-trimethylsilyloxy-9-aza-10-boraphenanthrene. It reacts with free phenolic steroids during the analysis of conjugated estrogen tablets and injectable formulations by GLC.
Application
N,O-Bis(trimethylsilyl)hydroxylamine has been used as reagent for the preparation of N-(dialkyl phosphinoyl)hydroxylamines and migration of simple alkyl groups in rearrangement of their O-p-nitrobenzenesulfonates.

Treatment of 9-chloro-9-borafluorene with N,O-bis(trimethylsilyl)hydroxylamine results in 10-trimethylsilyloxy-9-aza-10-boraphenanthrene 6b. NMR spectroscopy shows that the expected antiaromatic 9-(trimethylsilyloxyamino)-9-borafluorene 5b rearranges to the formally aromatic phenanthrene 6b at room temperature.
