Benzene, 1-(diazomethyl)-2-methyl-, also known as 2-methyl-1-(diazomethyl)benzene, is an organic compound with the chemical formula C8H8N2. It is a derivative of benzene, featuring a methyl group at the 2-position and a diazomethyl group (-CHN2) at the 1-position. Benzene, 1-(diazomethyl)-2-methyl- is characterized by its aromatic structure and the presence of a diazo group, which is a highly reactive and unstable functional group. The diazo group is known for its ability to participate in various chemical reactions, such as coupling reactions, which are important in the synthesis of dyes and other organic compounds. Due to the reactivity of the diazo group, 2-methyl-1-(diazomethyl)benzene is typically handled with care in laboratory settings to prevent unwanted reactions or decomposition.

698-20-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 698-20-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 698-20:
(5*6)+(4*9)+(3*8)+(2*2)+(1*0)=94
94 % 10 = 4
So 698-20-4 is a valid CAS Registry Number.

Iterative reactions of transient boronic acids enable sequential C-C bond formation

Battilocchio, Claudio,Feist, Florian,Hafner, Andreas,Simon, Meike,Tran, Duc N.,Allwood, Daniel M.,Blakemore, David C.,Ley, Steven V.

, p. 360 - 367 (2016/04/04)

The ability to form multiple carbon-carbon bonds in a controlled sequence and thus rapidly build molecular complexity in an iterative fashion is an important goal in modern chemical synthesis. In recent times, transition-metal-catalysed coupling reactions

Laser flash photolysis (LFP, XeCl, 308 nm, 20 ns) of phenyldiazomethane (PDM), o-tolydiazomethane (TDM) and mesitydiazomethane (MDM) produces phenylcarbene (PC), o-tolycarbene (TC) and mesitylcarbene (MSC), respectively. Transient spectra of PC and TC cou

Advantageous Syntheses of Diazo Compounds by Oxidation of Hydrazones with Lead Tetraacetate in Basic Environments

Holton, Terrence L.,Shechter, Harold

, p. 4725 - 4729 (2007/10/02)

Varied sensitive diazo compounds 3 are produced efficiently and safely in 3-6 g quantities by oxidation (eq 1) of hydrazones 1 at -78 deg C with lead tetraacetate (2) in triethylamine/chloroform, N-methylmorpholine/dimethylformamide, tetramethylguanidine (8)/dimethylformamide, and tetramethylguanidine/methylene chloride, respectively, upon use of appropriate workup and handling techniques.New and improved nonhazardous procedures have been developed for preparing and handling hydrazones 1 from aldehydes and ketones in reactions with excess hydrazine.
