As bis-trimethylsilylated N-methylhydroxylamine N-Methyl-N,O-bis(trimethylsilyl)- hydroxylamine can convert aldehydes and ketones to N-methyl nitrones with regio- and chemoselectivity; source of methylnitrene by pyrolysis; source of the trimethylsilyl(methyl)aminyl radical by photolysis.

It is obtained in 52% yield by reaction of Nmethylhydroxylamine with chlorotrimethylsilane (2.0 equiv) and triethylamine (3.3 equiv) in ether at 25 °C.
