Tetramethylguanidinium Azide TMGA

In 1966 tetramethylguanidinium azide (TMGA) (28) was prepared as an hydroscopic colourless, but stable, crystal by treatment of TMG (1) with hydrogen azide and was introduced by Papa [104] as a reactive azidation reagent (Table 4.17). [Pg.131]

The reaction of 1-arylsulfonylbicyclobutanes with TMGA (28) in A-methyl-2-pyrroli-done (NMP) or DMF at 80-90 °C regiospecifically produced cyclobutanes as a separable mixture of cis and trans isomers in high yield. Selected results are given in Table 4.18 [ 105]. [Pg.133]

Reactions using various azidation reagents were compared, among which TMGA (28) was found to be the most effective reagent for a desired displacement reaction [106] (Table 4.19). [Pg.133]
