4-(溴甲基)异硫氰酸苯酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: N-bromosuccinimide (6.26 g) (supplied from Tokyo Chemical Industry) and 1.13 g of 70% benzoyl peroxide (supplied from Aldrich) were added to a solution of 5.02 g of p-tolyl isothiocyanate (supplied from Tokyo Chemical Industry) in 100 mL of carbon tetrachloride, and stirred with heating reflux for 19 hours. The reaction suspension was filtrated and the filtrate was concentrated. The residue was applied onto the silica gel column and eluted with hexane, to yield 4.85 g of the title compound. with heating reflux for 19 hours The reaction suspension was filtrated the filtrate was concentrated eluted with hexane

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The procedure in the step a in Example 9 was followed except that instead of 3-bromopropyl isothiocyanate, 4-(bromomethyl)phenyl isothiocyanate (is-14 mentioned earlier) was used and instead of quinuclidine, N,N-dimethylbenzylamine (ta-32 mentioned earlier) was used to obtain the title compound.
