XeF2 reacted at room temperature in dichloromethane in the presence of HF with triphenylethene, 9-benzylidenefluorene and tetraphenylethene to form vicinal difluorides in high yield, the relative reactivities being in the following order: 1,1-diphenylethe

Crystalline stilbene (1) adds gaseous chlorine and bromine without intermediate melting.The stereoselectivity is similar to that observed in solutions.Triphenylethene (3) also yields the products 4 in gas-solid reactions with chlorine and bromine, but these products tend to loose HX from the crystal; their conversion products are described.Neither crystalline 1 nor 3, but (E)-1,2-diphenyl-1-propene (7) adds gaseous hydrogen bromide regiospecifically.The same is true for the crystalline chalcone 10, which adds hydrogen bromide and -chloride selectively to give 11 nonisotypically.Gaseous ammonia reconverts crystalline 11 into 10.The enamide 12 in its crystalline state adds the gases hydrogen bromide, -chloride, methanethiol and hydrogen, to give the products 13, but also 15 (addition and condensation) and 16 (double addition). 13f which is formed via hydrogenation of crystals is not isotypical with its precursor 12.The liquid 17 crstallizes on freezing and then easily adds the gases hydrogen bromide (> - 50 deg C) and hydrogen chloride (> - 80 deg C) in highly controlled reactions to give the reactive compounds 18.These are converted not only into oligomers but also into the derivatives 19, 20, 21, and 22.The advantages of the unusual reaction procedures are discussed.
