3354-42-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3354-42-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,5 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3354-42:
(6*3)+(5*3)+(4*5)+(3*4)+(2*4)+(1*2)=75
75 % 10 = 5
So 3354-42-5 is a valid CAS Registry Number.

Sulfur/DABCO Promoted Reductive Coupling/Annulation Cascade Reaction between o -Hydroxy/Amino Nitrobenzenes and Benzaldehydes

Dang, Minh-Huy Dinh,Nguyen, Linh Ho Thuy,Tran, Phuong Hoang

supporting information, p. 1687 - 1694 (2020/05/25)

Sulfur/DABCO was found to be an efficient reagent in promoting- the reductive coupling/annulation of o -nitrophenols or o -nitroanilines with benzaldehydes. This method represents a simple, straightforward, and green approach to the construction of benz-oxazoles and benzimidazoles.

1,1'2,2'-Tetrathiafulvalenes, III. - Syhthesis, Properties, and Reactions of 3,3'-Bi(3H-1,2-dithiolylidenes)(1,1',2,2'-Tetrathiafulvalenes)

Behringer, Hans,Meinetsberger, Eike

, p. 1928 - 1959 (2007/10/02)

1,1',2,2'-tetrathiafulvalenes 1 can be prepared by different methods from the cations of 1,2-dithiolylium salts 4 which are either unsubstituted or appropriate substituted in 3-position (instead of 3-Cl also H or SCH3).The structure of 1 is substantiated by chemical arguments.IR and 13C-NMR spectra support the absence of thioxo groups. - Like the 1,1',3,3'-isomers 2 the 1,1',2,2'-tetrathiafulvalenes are disposed to stepwise donation of electrons with formation of the radical cation and dication salts 25 or 11, respectively, as well as to the formation of charge transfer complexes with tetracyanoethylene, tetracyanoquinodimethane, and 2,3-dichloro-5,6-dicyanobenzoquinone.Tris(triphenylphosphine)rhodium(I) chloride and tetrakis(triphenylphosphine)platinum(O) yield complexes with 1a. - Thermolysis of 1 produces thienothiophenes 6.Partial desulfuration of 1a, for example, is also feasible with oxidizing agents like lead(IV) acetate.Selenium dioxide, however, gives the corresponding thienofuran 41.The reaction with trialkyl phosphites yields a disulfide - probably the 2,2'-bi(2H-thietylidene) 38 - the thermolysis of which gives the thienothiophene 6a. - Compounds 1a and 1c do not react with dimethyl acetylenedicarboxylate, isothiocyanate, several 1,3-dipoles (azides), and also not with elementary sulfur, however, 1e forms with sulfur the 3H-1,2-dithiol-3-thione 5e (X = S).
