2-Spiro-indan-1,3-dione

Monatshefte f�r Chemie, 1981
The reaction of 1,3-indandione, formaldehyde and primary amines does not gives doubleMannich bases as described in literature, but the title compounds.

13C NMR shifts and conformations of substituted indans

, 1983
13C NMR spectra of indan derivatives bearing substituents in the 1, 2, 5 and 6 positions are reported and assigned by LIS measurements and other techniques.

Polymers with indane units by cationic polymerization

Makromolekulare Chemie. Macromolecular Symposia, 1992
AbstractIn spite of the difunctionality of the monomers, cationic polymerization of 1,3‐ and 1,4‐diisopropenylbenzene does not lead to branched or cross‐linked products. Instead, soluble polymers are obtained, containing the 1,1,3‐trimethylindane system as repetitive unit along the backbone.

The stabilization of gallane and indane by a ring expanded carbene

Dalton Transactions, 2015
7Dipp Complexes of GaH3 and InH3 have been prepared. Despite high thermal stability in the solid state, both adducts decompose readily in solution at ambient temperature.

Reactions of Indan over Zeolite Catalysts

Industrial & Engineering Chemistry Research, 2010
The reactions of indan were studied over ZSM-5, zeolite β, and mordenite under atmospheric pressure or 3 MPa. Zeolite β shows the best catalytic activity. The main reaction pathways of indan are five-membered ring opening and condensation. The ring-opening reaction of indan follows β scission mechanism. No hydrogenation of indan occurs.

An Environmentally Friendly Synthesis of Functionalized Indans Using Electrochemical Cyclization of ortho‐Halo‐Substituted Homoallyl Ethers and Esters.

, 2006
The electrochemical cyclization of a series of ortho-halo-substituted homoallyl ethers and esters to functionalized indanes catalyzed by Ni(II) catalyst precursors derived from Ni(cyclam)Br 2 , (cyclam = 1,4,8,11-tetraazacyclotetradecane) and Ni(tmc)Br 2

The synthesis of indan-1-ones and isocoumarins

Journal of the Chemical Society, Perkin Transactions 1, 1981
A flexible synthetic route leading via indan-1-ones to variously methylated and oxygenated isocoumarins is described. The indanones are prepared by alternative routes involving intramolecular Friedel–Crafts cyclisation of aryl-propionic acids or pericyclic ring closure of acrylophenones.

Some derivatives of indan-1-one

Journal of the Chemical Society C: Organic, 1966
The structures of two compounds derived from indan-1-one, which had been in doubt, have been determined by n.m.r. spectrometry.

Conformational analysis of 2-aminoindans and 2-(aminomethyl)indans in relation to their central dopaminergic effects and a dynamic dopamine receptor concept.

Journal of Medicinal Chemistry, 1987
Conformational analyses on differently substituted 2-aminoindans of significant pharmacological interest were carried out by the molecular mechanics method (MM2).
