Reactivity Profile

Thioisocyanates, such as Thiazole, are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat.

An Efficient Synthesis of 1,3-Thiazole

The cyclocondensation of methyl dithiocarbamate with chloroacetaldehyde in aqueous ethanol affords 2-methylthio-1,3-thiazole (82-88percent) which is demethylsulfenylated to 1,3-thiazole (78-81percent) by reaction with lithium in liquid ammonia followed by hydrolysis with aqueous ammonia chloride.

Protodeboronation of (Hetero)Arylboronic Esters: Direct versus Prehydrolytic Pathways and Self-/Auto-Catalysis

The kinetics and mechanism of the base-catalyzed hydrolysis (ArB(OR)2→ ArB(OH)2) and protodeboronation (ArB(OR)2→ ArH) of a series of boronic esters, encompassing eight different polyols and 10 polyfluoroaryl and heteroaryl moieties, have been investigated by in situ and stopped-flow NMR spectroscopy (19F,1H, and11B), pH-rate dependence, isotope entrainment,2H KIEs, and KS-DFT computations. The study reveals the phenomenological stability of boronic esters under basic aqueous-organic conditions to be highly nuanced. In contrast to common assumption, esterification does not necessarily impart greater stability compared to the corresponding boronic acid. Moreover, hydrolysis of the ester to the boronic acid can be a dominant component of the overall protodeboronation process, augmented by self-, auto-, and oxidative (phenolic) catalysis when the pH is close to the pKaof the boronic acid/ester.

Reduction of Aryl Halides into Arenes with 2-Propanol Promoted by a Substoichiometric Amount of a tert-Butoxy Radical Source

Aryl halides are reduced into the corresponding arenes in high yields, using 2-propanol, cesium carbonate, and di-tert-butyl peroxide (or di-tert-butyl hyponitrite) as a reductant/solvent, a base, and a radical initiator, respectively. This simple system reduces a wide variety of aryl bromides, chlorides, and iodides through single-electron-transfer mechanism with high functional-group tolerance.

Photocatalytic Generation of 2-Azolyl Radicals: Intermediates for the Azolylation of Arenes and Heteroarenes via C-H Functionalization

The 2-azolyl radical, generated from 2-bromoazoles via photocatalysis, is a powerful intermediate for the intermolecular arylation of unmodified (hetero)arenes. The reaction is characterized by mild conditions, operational simplicity, tolerance toward functional and sterically demanding groups, broad scope, and anti-Minisci selectivity. A working mechanism is provided, and a low-solubility amine is essential for successful coupling. The utility of the reaction is demonstrated via late-stage functionalization of methyl estrone and application toward other bromoarenes.

Rhodium-catalyzed 2-methylthiolation reaction of thiazoles/oxazoles using 2-(methylthio)thiazole

RhH(PPh3)4 and 1,3-bis(dicyclohexyl)phosphinopropane (dcypp) catalyze the 2-methylthiolation of oxazoles and thiazoles using 2-(methylthio)thiazole as a thiolating reagent. The methylthio transfer reaction is under equilibrium, and various 2-methylthiolated thiazoles and oxazoles were obtained in moderate to good yields by removing thiazole under refluxing o-dichlorobenzene.

Reductive Alkylation of 2-Bromoazoles via Photoinduced Electron Transfer: A Versatile Strategy to Csp2-Csp3 Coupled Products

Access to Csp2-Csp3-coupled products is a challenging goal at the forefront of catalysis. The photocatalytic reductive coupling of aryl bromides with unactivated alkenes is introduced as a convenient method that circumvents any need for synthesis of sp3-hybridized coupling partners. The reaction takes place via photoinduced electron transfer from a tertiary amine to an aryl bromide that fragments to provide an aryl radical and subsequently reacts with an alkene to form a C-C bond. Conveniently, the amine also serves as the final reductant. The method is operationally simple, functional group tolerant, and takes place with selectivities that will allow it to be used in the context of complex molecule synthesis.
