N-Methyl-N,O-bis(trimethylsilyl)hydroxylamine Chemical Properties, Uses, Production
Physical properties
bp 40–41 °C/10 mmHg; n20 D 1.4146.2
Uses
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.
Preparation
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.
storage
N-Methyl-N,O-bis(trimethylsilyl)hydroxylamine is hydrolyzes readily upon exposure to moisture; stored without decomposition for several months in a sealed bottle at -10 to -15 °C; relatively thermally stable, having t1/2 of 46.5 h at 140 °C; dec at 180-190 °C.
