1122-17-4 Usage

Uses

Dichloromaleic Anhydride is a derivative of Maleic Anhydride (M124400) found to have considerable antifungal activity against Botrytis cinerea.

Purification Methods

Purify the anhydride by sublimation in vacuo [Katakis et al. J Chem Soc, Dalton Trans 1491 1986]. It has also been purified by Soxhlet extraction with hexane, recrystallised from CHCl3 and sublimed [MS, Relles J Org Chem 37 3630 1972]. [Beilstein 17/11 V 63.]

Check Digit Verification of cas no

The CAS Registry Mumber 1122-17-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1122-17:
(6*1)+(5*1)+(4*2)+(3*2)+(2*1)+(1*7)=34
34 % 10 = 4
So 1122-17-4 is a valid CAS Registry Number.

Benzopyrazinoisoindigo or Its Reduced Form? Synthesis, Clarification, and Application in Field-Effect Transistors

Wang, Xiao,Zhao, Zhiyuan,Ai, Na,Pei, Jian,Liu, Yunqi,Wan, Xiaobo

, p. 2603 - 2607 (2016)

Benzopyrazinoisoindigo, a pigment reported 40 years ago, should be a good candidate for n-type semiconductors if the reported structure is correct. Reinvestigation of this molecule revealed that it is actually (4H,4′H)-benzopyrazinoisoindigo, which could be considered as the reduced form of benzopyrazinoisoindigo, and hence, it is a good candidate for p-type semiconductors. The route toward the synthesis of this molecule was optimized, and a mechanism was accordingly proposed. A field-effect transistor based on this material showed a hole mobility up to 2.5 × 10-2 cm2 V-1 s-1. An expedient route for the synthesis of unexpectedly alkylated (4H,4′H)-benzopyrazinoisoindigo is developed, which also clarifies the previously reported structure. A mechanism is accordingly proposed. A field-effect transistor based on this material shows a hole mobility up to 2.5 × 10-2 cm2 V-1 s-1.

First Stereoselective Total Synthesis of a Dimeric Naphthoquinonopyrano-γ-lactone: (+)-γ-Actinorhodin

Neumeyer, Markus,Brückner, Reinhard

supporting information, p. 3383 - 3388 (2017/03/17)

We have accomplished the first total synthesis of an isomerically pure naphthoquinonopyrano-γ-lactone dimer, γ-actinorhodin, in eleven steps. Two steps exploit pairs of peri-MeO groups as unusual selectivity controls. The respective MeO groups convey the steric bulk of a bromo or iodo substituent located ortho to one MeO group as steric hindrance into the vicinity of the second MeO group. This relay effect was indispensable for exerting regiocontrol in an aromatic bromination and diastereocontrol in an oxa-Pictet–Spengler cyclization. The absolute configuration of our target compound was established in an asymmetric Sharpless dihydroxylation of a β,γ-unsaturated ester, which was synthesized in a Heck coupling of a bromoiodonaphthalene with ethyl vinylacetate. The dihydroxylation provided the γ-hydroxylactone moiety of the bromonaphthalene that was used as the substrate in the oxa-Pictet–Spengler cyclization. Dimerization to the core of γ-actinorhodin occurred by two Suzuki couplings.
