36804-63-4 Usage

General Description

1-Bromo-9H-fluoren-9-one, also known as 9-Bromo-9-fluorenone, is a chemical compound with the molecular formula C13H7BrO. It is a yellow crystalline solid that is insoluble in water and is primarily used in organic synthesis as a reagent to introduce the bromine functional group into other compounds. It is also utilized as an intermediate in the production of pharmaceuticals and agrochemicals. The compound is considered toxic and can cause irritation to the skin, eyes, and respiratory system upon contact. Additionally, it may have harmful effects on aquatic organisms and the environment if not handled and disposed of properly.

Check Digit Verification of cas no

The CAS Registry Mumber 36804-63-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,8,0 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 36804-63:
(7*3)+(6*6)+(5*8)+(4*0)+(3*4)+(2*6)+(1*3)=124
124 % 10 = 4
So 36804-63-4 is a valid CAS Registry Number.

Combined directed ortho metalation - Intramolecular Friedel-Crafts connections. Regiospecific route to 1-substituted fluoren-9-ones

Tilly, David,Samanta, Subhendu S,Faigl, Ferenc,Mortier, Jacques

, p. 8347 - 8350 (2002)

ortho-Substituted-2-biphenyl carboxylic acids of the type 3a-j were prepared by the tandem metalation sequence from 2-biphenyl carboxylic acid 1 with sec-butyllithium in THF at -78°C followed by quenching with electrophiles. The carboxylic acids 3a-f were converted into 1-substituted fluorenones 4a-f upon treatment with methanesulfonic acid.

C1-Linked Spirobifluorene Dimers: Pure Hydrocarbon Hosts for High-Performance Blue Phosphorescent OLEDs

Sicard, Lambert J.,Li, Hong-Cheng,Wang, Qiang,Liu, Xiang-Yang,Jeannin, Olivier,Rault-Berthelot, Jo?lle,Liao, Liang-Sheng,Jiang, Zuo-Quan,Poriel, Cyril

supporting information, p. 3848 - 3853 (2019/02/24)

Reported here are C1-linked spiro-bifluorene dimers. A comprehensive study is carried out to analyze the electronic properties of these highly twisted structures. This work shows that the C1-position enables the design of pure hydrocarbon materials, with a high triplet energy, for hosting blue phosphors in efficient phosphorescent OLEDs (PhOLEDs). To date, this work describes the highest performance of blue PhOLEDs ever reported for pure hydrocarbons (external quantum efficiency of ca. 23 %), thus highlighting the potential of the C1-spirobifluorene scaffold in organic electronics.

The expedient and regioselective metalation of unprotected biphenyl-2-, -3-, and -4-carboxylic acids

Tilly, David,Samanta, Subhendu S.,Castanet, Anne-Sophie,De, Asish,Mortier, Jacques

, p. 174 - 182 (2007/10/03)

Unprotected biphenyl-2-carboxylic acid can be cleanly metalated with sec-butyllithium at the position adjacent to the carboxylate and can then be subjected to site-selective electrophilic substitution. The remote C2′-position is attacked by the superbasic
