Descrizione

Applicazioni

Dimethylamine can be used:

• In the preparation of 1-organyl-1-(trimethylsiloxy)-2-(dimethylamino)ethenes starting from α-bromo ketones.
• In one of the key synthetic steps for the preparation of 1-methoxycarbonylpyrrolizin-3-one and its associated compounds.
• Ni-catalyzed cross-electrophile coupling of Katritzky pyridinium salts with bromoalkanes through C-N bond activation.
• To synthesize tertiary amides which on reaction with Petasis reagent followed by bromination forms bromomethyl ketones.
