56048-50-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 56048-50-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,0,4 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56048-50:
121 % 10 = 1
So 56048-50-1 is a valid CAS Registry Number.

Synthesis, photo- and electro-luminescence of red-emitting Ir(III) complexes with 2-(1-naphthyl)benzothiazole and carrier transporting group-functionalized picolinate ligands

Yu, Tianzhi,Bao, Yanjun,Zhao, Yuling,Zhang, Hui,Xu, Zixuan,Wu, Xiaomeng

, p. 33 - 40 (2016)

Two new red-emitting Ir(III) complexes containing 2-(1-naphthyl)benzothiazole as cyclometalated ligands and the carrier transporting group-functionalized picolinate as ancillary ligands have been successfully synthesized and characterized. The Ir(III) complexes have good thermal stability with less than 2% weight-reduction occurring at 285 °C, and exhibit strong red emissions. The doped light-emitting devices using the Ir(III) complexes as dopants were fabricated. The result indicated that the light-emitting devices fabricated by the carbazole-functionalized complex and the diaryl-1,3,4-oxadiazole-functionalized complex exhibited red emissions with a maximum brightness of 3074 and 2520 cd/m2at 10.7 V and a maximum current efficiency of 4.84 and 5.18 cd/A, respectively.

Room temperature HFIP/Ag-promoted palladium-catalyzed C–H functionalization of benzothiazole with iodoarenes

Bhujbal, Yuvraj,Gharpure, Santosh J.,Kapdi, Anant R.,Kommyreddy, Saidurga Prasad,Kori, Santosh,Vadagaonkar, Kamlesh

supporting information, p. 847 - 850 (2022/02/01)

A versatile synthetic protocol involving the room temperature direct arylation of benzothiazole with a wide variety of iodoarenes under Ag-promoted Pd-catalyzed conditions in HFIP as the reaction solvent has been presented. A sequential HFIP-promoted sele

Ultrasound-assisted efficient and green synthesis of 2-substituted benzothiazoles under solvent-free condition using recyclable sulfated tungstate

Pise, Ashok S.,Ingale, Ajit P.,Dalvi, Navnath R.

supporting information, p. 3629 - 3641 (2021/10/12)

Sulfated tungstate catalyzed an efficient and ecofriendly protocol has been described for the synthesis of 2-substituted benzothiazoles. The corresponding benzothiazoles were obtained using a condensation reaction of 2-aminothiophenol with various aldehydes under ultrasound irradiation at room temperature. Various functional groups on the 2-aminothiophenol as well as on the aldehydes were tolerated to provide 2-substituted benzothiazoles derivatives in excellent yields. The faster reaction rate, solvent-free or mild reaction conditions, wide functional group compatibility, excellent yields, easy work-up procedure, and excellent catalyst recyclability are the advantages of this protocol. These advantages make this process more practicable, cost-effective, and environmentally benign.
