The acidic solution, containing the 2-(2-dimethylaminoethyl)-1- [l-(2-pyridyl)-ethyl] -indan-Tol is heated on the steam bath for thirty minutes to effect dehydration to the desired indene derivative. The solution is cooled, made strongly basic with an aqueous solution... 

At 15 mm pressure the excess of 2-ethylpyridine is removed, at 120°C/0.5 mm some unreacted 2-(2-dimethylaminoethyl)-indene distills and at 165°-175°C/0.5 mm the 2-(2-dimethyl-aminoethyl)-3-[1-(2-pyridyl)-ethyl]-indene is collected. It may be converted to an aqueous solution of the dihydrochloride by dissolving it in the appropriate amount of dilute hydrochloric acid. 

To a solution of 1.0 gram of 2-(2-dimethylaminoethyl)-3-[ 1-(2-pyridyl)-ethyl]-indene in 10 ml of ethanol is added while stirring and heating 0.4 gram of maleic acid. On cooling the 2-(2-dimethylaminoethyl)-3-[ 1-(2-pyridyl)-ethyl]-indene maleate crystallizes, is filtered off, washed with a small amount of ethanol and recrystallized from ethanol, MP 158°C.

Triplet photoaddition of simple non-cyclic monoolefins is unknown. The sensitized dimerization of ethyl vinyl ether gives exclusively head-to-head adducts, Eq. 21, and probably should not be classed as an example of simple acyclic olefin. Usually the triplets have high energies and are severly twisted. 55> Some cyclic rigid molecules, Eq. 20, that do dimerize 63> do not incorporate substituents that allow regioselectivity to be determined. Butadiene gives principally head-to-head dimerization, Eq. 19, concordant with the PMO prediction, and so does indene, Eq. 22. The anti dimer that is formed would not be expected from a singlet excimer reaction. 

Styrene was purified and dosed as described [2]. Indene (99% + pure, Aldrich, Gold Label) was dried on CaH2 and dosed into evacuated phials. Ethyl vinyl ether and CEViE were Aldrich products. They were dried on CaH2 and used without further treatment. PhViE was prepared and purified essentially according to the method described [6] and stored over CaH2. 

The difficulty of distinguishing mechanisms at the ElcB-E2 borderline has also been discussed for reactions of secondary halides (1-X and 2-X) which feature a f-hydrogen made acidic by incorporation of an a-indenyl substituent (Scheme 1). 1,2-Elimination reactions of (/f,5 )-l-(l-X-ethyl)indene (1-X, X = Cl, Br, I, OBs) and the corresponding R,R isomers (2-X) promoted by water containing 25 vol.% acetonitrile...
