Ethane, 2-bromo-1,1-diethoxy- → HCID 21493040, compound

Participants

Reaction Steps

0.01 mole of sulphamide in 5 ml of concentrated hydrochloric acid is added to 0.012 mole of bromoacetaldehyde-diethylacetal, at room temperature whilst stirring. After 5 minutes, the precipitate which has formed is filtered off and washed with ice water, dried and recrystallised from acetone/petroleum ether. 3,7-Di-(bromomethyl)-1,5-dithia-2,4,6,8-tetra-aza-cyclooctane-1,1,5,5-tetraoxide is obtained as colourless needle-shaped crystals of melting point 172° C (decomposition) in a yield of 60%.
