81778-09-8 Usage

Uses

2-Chloro-5-fluorobenzyl bromide may be used to synthesize 2-chloro-5-fluorobenzaldehyde.

General Description

2-Chloro-5-fluorobenzyl bromide can be obtained by reacting 2-chloro-5-fluorotoluene with N-bromosuccinimide.

Check Digit Verification of cas no

The CAS Registry Mumber 81778-09-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,7 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81778-09:
(7*8)+(6*1)+(5*7)+(4*7)+(3*8)+(2*0)+(1*9)=158
158 % 10 = 8
So 81778-09-8 is a valid CAS Registry Number.

Synthesis and biological evaluation of new cytotoxic indazolo[4,3-gh] isoquinolinone derivatives

Shahabi, Manochehr,Schirmer, Eva,Shanab, Karem,Leepasert, Theerachart,Ruzicka, Jana,Holzer, Wolfgang,Spreitzer, Helmut,Aicher, Babette,Schmidt, Peter,Blumenstein, Lars,Müller, Gilbert,Günther, Eckhard

, p. 1846 - 1852 (2013/04/10)

A series of indazolo[4,3-gh]isoquinolinones derivatives have been synthesized to decrease cardiotoxic side effects in comparison to Mitoxantrone. The antiproliferative effects of different side chains were investigated and tested on at least four different cell lines of cervix, ovarian, CNS, NSCLC (non-small-cell lung cancer) and colon carcinoma. In addition to antiproliferative activities, influence on cell cycle and intercalation behavior have been tested.

An Unusual Fluorine Atom Rearrangement in the Photocyclization of 1-Fluorohelicenes

Mallory, Frank B.,Mallory, Clelia W.

, p. 526 - 532 (2007/10/02)

Oxidative photocyclization of 1-fluorohelicene and two of its chlorine-substituted derivatives leads to the formation of 8-fluorobenzoperylenes through an unprecedented inter-ring fluorine atom migration; photoelimination of HF to give benzoperylenes also occurs as a competing process.The rearrangement pathway predominates when the irradiation is carried out at 0 deg C in air-saturated benzene solution containing 10 -3 M iodine; the elimination pathway predominates at higher temperatures or in the absence of either oxygen or iodine.The rearrangement isrationalized by postulating a triplet-state photocyclization to give a dihydrobenzoperylene intermediate, followed by abstraction of the tertiary hydrogen atom from that intermediate to give a radical that subsequently undergoes a fluorine atom shift by an SNi'mechanism.
