52341-51-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52341-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,3,4 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 52341-51:
92 % 10 = 2
So 52341-51-2 is a valid CAS Registry Number.

A simple and broadly applicable synthesis of fluorene-coupled D-σ-A type molecules: towards high-triplet-energy bipolar hosts for efficient blue thermally-activated delayed fluorescence

Li, Chuan,Du, Xiaoyang,Zhou, Yu,Ye, Jun,Fu, Lulu,Humphrey, Mark G.,Wu, Chao,Zhao, Juewen,Du, Yanqing,Tao, Silu,Wu, Jiacheng,Zhang, Chi

, p. 6949 - 6957 (2018)

An effective two-step synthesis of high-triplet-energy (ET) bipolar hosts that is simple and broadly applicable is introduced. Electron-donating (D = (9-phenyl-9H-carbazol-3-yl/4-(9H-carbazol-9-yl)phenyl)) and -accepting (A = (tetrafluoropyridin-4-yl/4,6-diphenyl-1,3,5-triazin-2-yl)) units have been coupled to the C9 atom of fluorene to afford the four hosts 3CzFTFP, 9PhFTFP, 3CzFDPhTz, and 9PhFDPhTz with sp3 C9-centered bulky ternary structures, excellent thermal/morphological stabilities, tunable abilities for bipolar charge carrier injection/transport, and identical high ET (2.87 eV). Blue thermally-activated delayed fluorescence (TADF) devices using these new hosts and 2CzPN as the host-guest system exhibited efficient electroluminescence efficiencies of 38 cd A-1/30 lm W-1/17%, which are among the best for 2CzPN-based TADF devices. The generality of this synthetic strategy to high-ET fluorene-coupled D-σ-A type hosts was confirmed by successfully appending other D/A groups ((diphenylamino)phenyl/phenylsulfonyl) to fluorene, affording TPAFBSO.

Lewis Acid Catalyzed [4 + 2] Cycloaddition of N-Tosylhydrazones with ortho-Quinone Methides

Wang, Chun-Ying,Han, Jia-Bin,Wang, Long,Tang, Xiang-Ying

, p. 14258 - 14269 (2019/11/11)

A formal [4 + 2] cycloaddition of N-tosylhydrazones with ortho-quinone methides was developed, affording the facile synthesis of diverse 1,3-oxazine derivatives under mild conditions. In this transformation, N-tosylhydrazones are used as a 1,2-dipole synt

Directed C-C bond cleavage of a cyclopropane intermediate generated from: N -tosylhydrazones and stable enaminones: Expedient synthesis of functionalized 1,4-ketoaldehydes

supporting information, p. 12286 - 12289 (2017/11/20)

An efficient method to construct functionalized 1,4-ketoaldehydes bearing all-carbon α-quaternary centers via regioselective C-C bond activation has been described. The cyclopropanation of bench-stable enaminones with in situ generated diazo reagents from
