Abstract: Novel fluorogenic and chromogenic three-dimensional ionophores are provided which selectively bond ions such as potassium, sodium, and lithium, even in neutral aqueous or alcohol media. The novel ionophores comprise an "ion-recognizing system" fused to a "signal-moiety" through one or more heteroatoms having a non-bonded electron pair. The signal-moieties are selected from the group consisting of fused ring heterocyclics, fused aromatics, and subsituted aromatics having at least one nitro or azo moiety. The ion-recognizing system is a three-dimensional cryptand. The ionophores are ideal for the selective and direct termination of ions in biological or environmental samples and the like.

Abstract: Novel fluorogenic ionophores have been synthesized which selectively bind ions such as potassium and sodium, even in neutral aqueous and alcoholic media and respond to such binding by fluorescence quenching or enhancement. These ionophores are ideal for the selective and direct determination of ions in biological or environmental samples and the like. The ionophores are also suitable for incorporation into fiber optic-based sensors for the continuous in vivo or in vitro monitoring of metal ions in blood or other biological fluids.

Preferred cycloalkanones, 2-alkyl- and 2-arylcyclohexanone are autoxidized in pulverized sodium hydroxide/dimethoxyethane to produce 6-alkyl- or 6-aryl-6-oxohexanoic acids, respectively.

Abstract: Methanol is reacted with branched monoolefins such as isobutylene, or mixtures of hydrocarbons such as mixed C-4's from or in a refinery, in the presence of methanesulfonic acid. A column (10) operation is described wherein methanesulfonic acid (11) and methanol (12) are fed in countercurrent fashion to hydrocarbons (13). Crude product ether is removed as a liquid sidestream (25) above the feed of methanesulfonic acid (11), while hydrocarbons depleted of the reactive branched monoolefins (24) are removed overhead. The methanesulfonic acid suppresses the vapor pressure of methanol relative to product ether.

Conjugated dienic hydrocarbons, including alkyl cyclohexa-1,3-dienes, are converted to beta-olefinic peroxides by sulfur dioxide and oxygen. The aromatization reactions are useful as part of the synthesis of selected aromatics from acyclic olefins. The beta-olefinic peroxides are useful intermediates in the production of 1,4-diols.
