In situ fluorescent labeling of highly volatile methylamine with 8-(4,6-dichloro-1,3,5-triazinoxy)quinoline

, p. 872 - 874 (2001)
The first in situ fluorescent labeling probe for monitoring of highly volatile methylamine, 8-(4,6-dichloro-1,3,5-triazinoxy)quinoline, has been designed, synthesized and evaluated. The probe labels spectroscopically inert methylamine, causing a large change in fluorescence properties through suppression of the internal charge transfer, and thus can serve as an in situ labeling probe. This applicability has been demonstrated by measuring methylamine released during hydrolysis of N-methylcarbamates such as ethiofencarb.
Iodine-Mediated Direct Generation of o-Quinone Methides at Room Temperature: A Facile Protocol for the Synthesis of ortho-Hydroxybenzyl Thioethers

An iodine-mediated preparation of ortho-quinone methides (o-QMs) from ortho-hydroxybenzyl alcohols by a C?O bond scission strategy is described. The in situ generated o-QMs were then employed for C?S bond formation by thio-Michael addition of thiols to provide the ortho-hydroxybenzyl thioethers (o-HBT) in moderate to excellent yields.

Reaction of a phenol with an aldehyde in the presence of phenylboronic acid gives a 1,3,2-benzodioxaborin.The latter could be reduced to the corresponding ortho-alkylphenol with tert-butylamine borane in the presence of aluminum chloride.Alternatively, the dioxaborin, when reacted with an alkylthiol or an alcohol in the presence of an acid, gave the corresponding ortho-alkylthiomethyl- or ortho-alkoxymethylphenol.Key words: phenol, alkylation, ortho-specific, 1,3,2-benzodioxaborin.
