The title compound, C(17)H(26)O, is a di-ortho-alkyl substituted phenyl ethanone that exhibits a significant twisting of the ketone fragment relative to the aromatic ring [O-C-C-C torsion angle = 89.32 (17)°] due to steric pressure from the ortho-isopropyl groups. One ortho- and the para-isopropyl group exhibit orientational disorder with a refined site occupancy factor of 0.562 (3):0.438 (3).

In a 4-isopropyl-1-oxa-3-oxonia-2-borata-naphthalene the isopropyl group exhibits the same conformational phenomena as the Me2N group in 8-dimethylamino-naphth-1-yl-silanes and related phosphorus compounds. Since the details can be fully rationalized on the basis of the steric situation and electronic factors are excluded, the common features cannot serve to infer dative interaction from nitrog...

The highly effective self-assembly process between 2,4,6-tris(isopropyl)phenylphosphine or mesitylphosphine, formaldehyde and 1,4-bis(alpha-(4'-aminophenyl)isopropyl)benzene results in the formation of a novel type of heterocyclophane which is able to encapsulate organic molecules as well as being a potential ligand for transition metals inside the intramolecular cavity. Compounds of this type ...

In developing of ointment for topical treatment of colds the structural and mechanical properties of the ointment bases contained isopropyl palmitate, beeswax and solid fat in different concentrations have been studied. Amount of isopropyl palmitate 60% remained constant and the ratio of solid fat and bee wax was varied. In order to study thixotropic properties the curve of kinetics deformation...

www.thelancet.com Vol 384 October 11, 2014 1345 as 1–2% chlorhexidine in isopropyl alcohol, but we agree with Maiwald and colleagues that adequate studies to support or reject this hypothesis have not yet been done. Chlorhexidine in an alcoholic solution, however, is clearly superior to povidone-iodine for prevention of vascular catheter-related bloodstream infec tion. Maiwald and colleagues ha...
