General Description

(E)-1,1'-[vinylenebis(thio)]bispropane is a chemical compound with the molecular formula C9H18S2. It is a symmetrical molecule with two thiol groups and a central carbon-carbon double bond. (E)-1,1'-[vinylenebis(thio)]bispropane is commonly used in the production of rubber and plastics, as well as in various organic synthesis reactions. It is also utilized as a vulcanization accelerator for rubber and as a chain transfer agent in the production of polymers. Additionally, it can be used as a crosslinking agent in the manufacture of adhesives and sealants. This chemical is known for its odor and is considered toxic if ingested or inhaled in large amounts. Proper safety precautions should be taken when handling and using (E)-1,1'-[vinylenebis(thio)]bispropane.

Check Digit Verification of cas no

The CAS Registry Mumber 1120-17-8 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 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1120-17:
(6*1)+(5*1)+(4*2)+(3*0)+(2*1)+(1*7)=28
28 % 10 = 8
So 1120-17-8 is a valid CAS Registry Number.

A Molecular Iron-Based System for Divergent Bond Activation: Controlling the Reactivity of Aldehydes

Chatterjee, Basujit,Jena, Soumyashree,Chugh, Vishal,Weyhermüller, Thomas,Werlé, Christophe

, p. 7176 - 7185 (2021/06/30)

The direct synthesis of amides and nitriles from readily available aldehyde precursors provides access to functional groups of major synthetic utility. To date, most reliable catalytic methods have typically been optimized to supply one product exclusively. Herein, we describe an approach centered on an operationally simple iron-based system that, depending on the reaction conditions, selectively addresses either the C=O or C-H bond of aldehydes. This way, two divergent reaction pathways can be opened to furnish both products in high yields and selectivities under mild reaction conditions. The catalyst system takes advantage of iron's dual reactivity capable of acting as (1) a Lewis acid and (2) a nitrene transfer platform to govern the aldehyde building block. The present transformation offers a rare control over the selectivity on the basis of the iron system's ionic nature. This approach expands the repertoire of protocols for amide and nitrile synthesis and shows that fine adjustments of the catalyst system's molecular environment can supply control over bond activation processes, thus providing easy access to various products from primary building blocks.

Synthesis of: N-acyl amide natural products using a versatile adenylating biocatalyst

Marchetti, Piera M.,Richardson, Shona M.,Kariem, Noor M.,Campopiano, Dominic J.

supporting information, p. 1192 - 1196 (2019/07/31)

Natural products are secondary metabolites produced by many different organisms such as bacteria, fungi and plants. These biologically active molecules have been widely exploited for clinical application. Here we investigate TamA, a key enzyme from the biosynthetic pathway of tambjamine YP1, an acylated bipyrrole that is produced by the marine microorganism Pseudoalteromonas tunicata. TamA is a didomain enzyme composed of a catalytic adenylation (ANL) and an acyl carrier protein (ACP) domain that together control the fatty acid chain length of the YP1. Here we show that the TamA ANL domain alone can be used to generate a range of acyl adenylates that can be captured by a number of amines thus leading to the production of a series of fatty N-acyl amides. We exploit this biocatalytic promiscuity to produce the recently discovered class of N-acyl histidine amide natural products from Legionella pneumophila.

Corresponding amine nitrile and method of manufacturing thereof

-

Paragraph 0138; 0139; 0140; 0141; 0142, (2018/05/07)

The invention relates to a manufacturing method of nitrile. Compared with the prior art, the manufacturing method has the characteristics of significantly reduced using amount of an ammonia source, low environmental pressure, low energy consumption, low production cost, high purity and yield of a nitrile product and the like, and nitrile with a more complex structure can be obtained. The invention also relates to a method for manufacturing corresponding amine from nitrile.
