The Haloform Reaction . Reynold

3,5,5,6,8,8-Hexamethyl-5,6,7,8-tetra­hydro-2-naphthoic acid (AHTN–COOH)

The title compound, C(17)H(24)O(2), is the product of a haloform reaction of 6-acetyl-1,1,2,4,4,7-hexa-methyl-tetra-line (AHTN). The compound is a racemic mixture with a disorder in its aliphatic ring [occupany ratio 0.683 (4):0.317 (4)] due to two possible half-chair forms. The carb-oxy-lic acid unit is slightly twisted out of coplanarity with the aromatic system [dihedral angle = 29.26 (6)°]....

Transformations of polycyclic musks AHTN and HHCB upon disinfection with hypochlorite: two new chlorinated disinfection by-products (CDBP) of AHTN and a possible source for HHCB-lactone.

In this work, the behavior of the polycyclic musks 6-acetyl-1,1,2,4,4,7-hexamethyltetraline (AHTN) and 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta-γ-2-benzopyran (HHCB) was investigated upon disinfection by using sodium hypochlorite as disinfectant in a model disinfection basin in order to find new disinfection by-products (DBP). In the case of AHTN, the carboxylic acid 3,5,5,6,8,8-h...

Disinfection by-products from halogenation of aqueous solutions of terpenoids.

We report the formation of trihalomethanes and other disinfection by-products from four polyfunctional terpenoids during simulated chlorination of natural waters. Complex suites of products were identified by closed loop stripping analysis (CLSA)/gas chromatography-mass spectrometry (GC-MS) from halogenation of beta-carotene and retinol. beta-Ionone appeared to be a key intermediate in the halo...
