1118-84-9 Usage

Chemical Properties

clear colorless to slightly yellow liquid

Flammability and Explosibility

Nonflammable

Check Digit Verification of cas no

The CAS Registry Mumber 1118-84-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,1 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1118-84:
(6*1)+(5*1)+(4*1)+(3*8)+(2*8)+(1*4)=59
59 % 10 = 9
So 1118-84-9 is a valid CAS Registry Number.

Ionic liquid-regulated sulfamic acid: Chemoselective catalyst for the transesterification of β-ketoesters

Bo, Wang,Ming, Yang Li,Shuan, Suo Ji

, p. 5037 - 5039 (2003)

1-Propyl-3-methylimidazolium chloride ([C3MIm]Cl) ionic liquid and sulfamic acid (NH2SO3H), as a synergetic catalytic medium, were used for the transesterification of acetoacetate with alcohols of different structures. It shows the good ability for the chemoselective transesterificatin of β-ketoesters and maintains its catalytic activity in the reuse.

Zinc mediated transesterification of β-ketoesters and coumarin synthesis

Chavan, Subhash P,Shivasankar,Sivappa,Kale, Ramesh

, p. 8583 - 8586 (2002)

The transesterification of ketoesters using zinc and iodine is described. The reaction has been done on a variety of alcohols and phenols. Alcohols furnish transesterified products whereas phenols gave 4-methylcoumarins. The method is highly promising compared with existing methods.

Niobium(V) oxide: A new and efficient catalyst for the transesterification of β-keto esters

De Sairre, Mirela Inês,Bronze-Uhle, érika Soares,Donate, Paulo Marcos

, p. 2705 - 2708 (2005)

Niobium(V) oxide is an efficient catalyst for the transesterification of β-keto esters with several kinds of alcohols, leading to good conversions. Moderate to good isolated product yields have been obtained at faster rates than those recently reported for various catalysts.

Mo-ZrO2 solid acid catalyst for transesterification of β-ketoesters

Reddy, Benjaram M.,Reddy, Vangala R.,Manohar, Basude

, p. 1235 - 1239 (1999)

An efficient and mild method for transesterification of β-ketoester catalyzed by Mo-ZrO2 solid acid catalyst is described.

BF3OEt2: An efficient catalyst for transesterification of β-ketoesters

Yang, Jinhui,Ji, Congbin,Zhao, Yanmin,Li, Yunfeng,Jiang, Shizhi,Zhang, Zhiwei,Ji, Yongqiang,Liu, Wanyi

, p. 957 - 963 (2010)

A facile and selective transesterification of β-ketoesters using BF3OEt2 as catalyst is described. The emphasis has been placed on the reaction of methyl acetoacetate with a series of alcohols of different structures, leading in all cases to good to excellent yields.

Visible-light-driven radical 1,3-addition of selenosulfonates to vinyldiazo compounds

Li, Weiyu,Zhou, Lei

supporting information, p. 6652 - 6658 (2021/09/10)

Herein, we report a visible-light-driven radical 1,3-selenosulfonylation of vinyldiazo compounds with selenosulfonates, providing various γ-seleno allylic sulfones in good yields. This photochemical reaction was carried out at room temperature in an open flask using ethyl acetate as the solvent without any photocatalysts or additives. The control experiments corroborated that the 1,3-addition proceeded via a radical-chain propagation process. The synthetic applications of the resulting products were demonstrated by deselenization, reduction, bromination and allylation.
