Phosphonium chloride as a non-volatile chlorinating reagent: Preparation and reaction in no solvent or ionic liquid

Reaction of triphenylphosphine with trichloroisocyanuric acid in no solvent or an ionic liquid gave the corresponding phosphonium chloride, which can be used as a cheap and safe chlorinating reagent. Conversion of hydroxyheterocycles to chloroheterocycles, carboxylic acids to carboxylic acid chlorides, and primary amides to nitriles were accomplished by using the phosphonium chloride in excellent to good yields.

Organocatalyzed, Photoredox Heteroarylation of 2-Trifluoroboratochromanones via C-H Functionalization

Heteroarylation via C-H functionalization has been synthetically challenging, but such transformations represent an atom-economical and highly convergent route toward complex molecules. Reported herein is a photoredox-catalyzed coupling between 2-trifluoroborato-4-chromanones and various heteroarenes through a Minisci pathway. Mesitylacridinium perchlorate, an organic photocatalyst, proved to be a better photocatalyst than transition-metal counterparts for such transformations. To highlight the utility of this approach, a library of unprecedented heteroaryl-substituted chromanones was generated that was composed of numerous, specifically substituted molecules containing a broad range of functional groups.

Synthesis of 2-(4-nitrophenoxy)quinoxaline and its reactions with hydroxide ion in micellar systems

The synthesis of 2-(4-nitrophenoxy)quinoxaline (3) is described. The reaction of (3) with hydroxide ion was studied in the presence and absence of micellar systems. Cationic micelles of cetyltrimethylammonium chloride and bromide (CTACl and CTABr) and tetradecyltrimethylammonium chloride and bromide (MTACl and MTABr) speed the reaction of (3) with hydroxide ion. The second-order rate constants at the micellar pseudophase are smaller than the second-order rate constant in water.

Metal-, Photocatalyst-, and Light-Free Minisci C-H Alkylation of N-Heteroarenes with Oxalates

Herein, we report a mild protocol for metal-, photocatalyst-, and light-free Minisci C-H alkylation reactions of N-heteroarenes with alkyl oxalates derived from primary, secondary, and tertiary alcohols. The protocol uses environmentally benign persulfate as a stoichiometric oxidant and does not require high temperatures or large excesses of either of the substrates, making the procedure suitable for late-stage C-H alkylation of complex molecules. Notably, several pharmaceuticals and natural products could be functionalized or prepared with this protocol, thus demonstrating its utility.

Preparation of nitrogen-containing pi-deficient heteroaromatic Grignard reagents: Oxidative magnesiation of nitrogen-containing pi-deficient halogenoheteroaromatics using active magnesium

The oxidative magnesiation of nitrogen-containing pi-deficient halogenoheteroaromatics using active magnesium was accomplished. Both magnesiation followed by addition of a carbonyl compound (Grignard reaction) and magnesiation in the presence of a carbonyl compound (Barbier reaction) were carried out to afford the corresponding product. Especially, the latter method enabled fused halogenodiazines such as 4-chloro-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine or 2-chloroquinoxaline to magnesiate at a mild temperature (-20 to 30 C).

Emission properties of diazines chromophores: Structure-properties relationship

This article presents the photophysical properties of a series of diazine chromophores. The influence of five parameters has been studied: the presence of a diazine/benzodiazine fragment, the nature of the diazine fragment (1,3-diazine/1,4-diazine), the presence or not of an vinyl linker between diazine ring and phenylene fragments of the pi-conjugated bridge, the presence of a phenylene/biphenylene linker and the nature of electron donating group (dimethylamino/diphenylamino). Taguchi’s design of experiment combined with analysis of variance methodologies have been employed to highlight the main structural parameters influencing the position of absorption and emission maxima of dichloromethane solution and the extend of emission solvatochromic range exhibited by this family of chromophores.
