The reaction between benzyl-triethyl-ammonium chloride and dimethyl-tin dichloride yields the title salt, [(C(6)H(5)CH(2))(C(2)H(5))(3)N](2)[SnCl(6)]. The Sn(IV) atom, located on a center of inversion, exists in an octa-hedral coordination environment. The cation links with the anion via weak C-H⋯Cl hydrogen bonding.

The Lewis acid-mediated reactions of allene-ene compounds, derived from 3-methylcitronellal or dimethyl malonate, were carried out using various Lewis acids such as ethylaluminum dichloride, diethylaluminum chloride, titanium chloride, zinc chloride etherate, or boron trifluoride etherate, affording unexpectedly intramolecular [2+2]cycloaddition products under some particular reaction condition...

The title compound, C(18)H(19)NO, was synthesized from the multi-component one-pot reaction between p-toluidine, benzaldehyde and 2,3-dihydro-furan in the presence of palladium dichloride. There are two mol-ecules in the asymmetric unit. The crystal packing is stabilized by classical inter-molecular N-H⋯O hydrogen bonds.

Vilsmeier reagent formed from phthaloyl dichloride and DMF was found to be very effective for converting 2-hydroxyacetophenones, deoxybenzoins and dihydrochalcones into corresponding chromones, isoflavones and homoisoflavones with excellent yield. This method offers significant advantages such as efficiency and mild reaction conditions with shorter reaction time.

While salicylates are among the most frequently prescribed drugs, methods for their determination in blood have been neither sufficiently sensitive nor precise. Brodie, Udenfriend, and Coburn (1) have devised a procedure suitable for the clinical measurement of blood salicylate levels if large doses are given. In their method the salicylate is extracted from acidified plasma with ethylene dichl...
