lambda5-Phosphorus-Containing alpha-Diazo Compounds: A Valuable Tool for Accessing Phosphorus-Functionalized Molecules

The compounds characterized by the presence of a lambda5-phosphorus functionality at the alpha-position with respect to the diazo moiety, here referred to as lambda5-phosphorus-containing alpha-diazo compounds (PCDCs), represent a vast class of extremely versatile reagents in organic chemistry and are particularly useful in the preparation of phosphonate- and phosphinoxide-functionalized molecules. Indeed, thanks to the high reactivity of the diazo moiety, PCDCs can be induced to undergo a wide variety of chemical transformations. Among them are carbon-hydrogen, as well as heteroatom-hydrogen insertion reactions, cyclopropanation, ylide formation, Wolff rearrangement, and cycloaddition reactions. PCDCs can be easily prepared from readily accessible precursors by a variety of different methods, such as diazotization, Bamford-Stevens-type elimination, and diazo transfer reactions. This evidence along with their relative stability and manageability make them appealing tools in organic synthesis. This Review aims to demonstrate the ongoing utility of PCDCs in the modern preparation of different classes of phosphorus-containing compounds, phosphonates, in particular. Furthermore, to address the lack of precedent collective papers, this Review also summarizes the methods for PCDCs preparation.

Highly efficient blue-emitting materials based on 10-naphthylanthracene derivatives for OLEDs

A series of new blue-emitting materials: 2-(10-(naphthalen-2-yl)anthracen-9-yl)pyridine (1); 1-(10-(naphthalen-2-yl)anthracen-9-yl)isoquinoline (2); 9-(3-(10-(naphthalen-2-yl)anthracen-9-yl)phenyl)-9H-carbazole (3); 9-(4-(10-(naphthalen-2-yl)anthracen-9-yl)phenyl)-9H-carbazole (4); 9-(4-(10-(naphthalen-1-yl)anthracen-9-yl)phenyl)-9H-carbazole (5); 9-(4?-(10-(naphthalen-2-yl)anthracen-9-yl)biphenyl-4-yl)-9H-carbazole (6); and 9-(4?-(10-(naphthalen-1-yl)anthracen-9-yl)biphenyl-4-yl)-9H-carbazole (7) were designed and synthesized via the Suzuki cross-coupling reaction. To explore the electroluminescent properties of these materials, multilayer OLEDs were fabricated in the following sequence: ITO/4,4?-bis(N-(1-naphthyl)-N-phenylamino)biphenyl (NPB) (50 nm)/blue-emitting materials (1-7) (30 nm) /4,7-diphenyl-1,10-phenanthroline (Bphen) (30 nm)/lithium quinolate (Liq) (2 nm)/Al (100 nm). Among those, a device using 6 as an emitter exhibited a high external quantum efficiency of 3.83% (3.20% at 20 mA/cm2) with CIE coordinates of (0.152, 0.114). In order to improve EL efficiency, 1-7 were used as blue host materials for blue dopant materials 4?-[2-(2-diphenylamino-9,9-diethyl-9H-fluoren-7-yl)vinyl]-p-terphenyl (PFVtPh) and 3-(N-phenylcarbazol)vinyl-p-terphenyl (PCVtPh). Using 1 as a host material for blue dopant material PFVtPh, the resultant device showed high EL efficiencies with 10.35 cd/A, 8.77 lm/W, and 5.70% (10.24 cd/A, 6.06 lm/W, and 5.66% at 20 mA/cm2). Furthermore, using 4 as a host for the PCVtPh blue dopant, device 4c exhibited efficient deep-blue emissions with a maximum external quantum efficiency of 2.96% and CIE coordinates of (0.154, 0.087), very close to the NTSC blue standard of (0.14, 0.08).

I2/TBHP mediated multiple C[sbnd]H bonds functionalization of azaarenes with methylarenes to synthesize iodoisoquinolinones via iodination/N-benzylation/amidation sequence

An oxidative multi-functionalization of azaarenes with benzylic C[sbnd]H bonds of methylarenes via iodination/N-benzylation/amidation cascade, to produce N-benzyl-4-iodoisoquinolin-1(2H)-ones and N-benzyl-3-iodoquinolin-2(1H)-ones is developed. The molecular iodine plays a triple role in activating benzylic sp3 C[sbnd]H bond of methylbenzenes, accelerating the oxidation process and serving as iodination reagent. This reaction utilizes cheap and readily available azaarenes and methylarenes as starting materials and proceeds under metal-free conditions to construct C-I, C[sbnd]N and C[dbnd]O bonds consecutively and afford iodo(iso)quinolinones efficiently.

Pd-catalyzed nucleophilic fluorination of aryl bromides

On the basis of mechanism-driven reaction design, a Pd-catalyzed nucleophilic fluorination of aryl bromides and iodides has been developed. The method exhibits a broad substrate scope, especially with respect to nitrogen-containing heteroaryl bromides, and proceeds with minimal formation of the corresponding reduction products. A facilitated ligand modification process was shown to be critical to the success of the reaction.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 4-Fluoroisoquinoline, you can also check out more blogs about394-67-2
