(Ritter: "isosafrole glycol less reactive than its formate", Chemistry Discourse).GC_MS: I do not doubt that polymerization occurs, but I do not think that these products will distill in the range observed for the glycol in a relatively pure form, as well as solidify in the condenser just like predicted for the glycol.
I am very interested in your references, particularly the Ind. J. Chem article, could you post it? The Berichte article I can fetch myself, and I have the "Friedel-Crafts and related reactions" book series on the attic, so I can get that tomorrow.
You can get some polymers distilled over, although I made the mistake to assume that every newbee can pull a 0.1 mmHg "vacuum" by a snap of the finger.
The Friedel-Crafts related indanes are interesting, since it seems they are found in plants as well. I only know of one such indane been discovered up till today, but I wouldn't be surprised if similar compounds would be present in essential oils with a high propenylbenzene content (eg anise and sassafras oil). Reference: DB Saxena, Phenyl indane from Acorus calamus. Phytochemistry 25(2) (1986) 553-556. It really is nothing more then the indane arising from a condensation between 2 molecules of asaron.
