Organic Gas‐Solid Reactions: Additions of HX to N ‐Vinylphthalimide and Substitutions of its Hydrate Gas‐solid additions of N ‐vinylphthalimide ( 1 ) and gas‐solid substitutions of its isolable hydrate 5 with the dipolar gases HCl, HBr, HI yield quantitatively and surprisingly rapidly the reactive halogeno compounds 2, 3, 4 , respectively. Their hydrolysis, depending on the conditions (gas: static, flow; liquid), gives 5 and the ether 7 , alcoholysis and acetolysis the alkoxy (acetoxy) derivatives 8 . Also gaseous bromine and (catalytically) water is added to crystalline 1 . The mechanism of the [1,2/2,1]rearrangement of N ‐(2‐bromoethyl)‐into N ‐(1‐bromoethyl)phthalimide is established as a sequence of HBr‐elimination and ‐addition.
