17950-66-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17950-66-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,5 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17950-66:
(7*1)+(6*7)+(5*9)+(4*5)+(3*0)+(2*6)+(1*6)=132
132 % 10 = 2
So 17950-66-2 is a valid CAS Registry Number.

Consecutive three- and four-component coupling-Bagley-Bohlmann-Rahtz syntheses of tri- and tetrasubstituted pyridines

Dohe, Janis,Müller, Thomas J. J.

, p. 705 - 718 (2016/07/06)

The concatenation of the modified Sonogashira alkynone synthesis and the Bagley-Bohlmann-Rahtz pyridine synthesis gives novel consecutive three- and four-component coupling-Bagley-Bohlmann-Rahtz (cBBR) syntheses of tri- and tetrasubstituted pyridines in a one-pot fashion. With these processes 15 differently substituted 3-ethoxycarbonyl 2-methylpyridines can be readily obtained in modest to moderate yields.

One-pot three-step synthesis of 1,2,3-triazoles by copper-catalyzed cycloaddition of azides with alkynes formed by a Sonogashira cross-coupling and desilylation

Friscourt, Frederic,Boons, Geert-Jan

supporting information; experimental part, p. 4936 - 4939 (2010/12/25)

A microwave-assisted, one-pot, three-step Sonogashira cross-coupling- desilylation-cycloaddition sequence was developed for the convenient preparation of 1,4-disubstituted 1,2,3-triazoles starting from a range of halides, acyl chlorides, ethynyltrimethyls

Palladium-Catalyzed Reactions of Acyl Chlorides with (1-Alkynyl)tributylstannanes. A Convenient Synthesis for 1-Alkynyl Ketones

Logue, Marshall W.,Teng, Kelly

, p. 2549 - 2553 (2007/10/02)

Acyl chlorides couple with (1-alkynyl)tributylstannanes in the presence of catalytic amounts of palladium(II) or palladium(0) complexes to produce 1-alkynyl ketones in respectable yields.The couplings of isobutyryl, acetyl, benzoyl, and p-nitrobenzoyl chlorides with phenylethynyl-, (trimethylsilyl)ethynyl-, (carbomethoxy)ethynyl-, -1-propynyl>-, and (3,3-diethoxy-1-propynyl)tributylstannanes were investigated in the presence of tetrakis(triphenylphosphine)palladium(O), benzylchlorobis(triphenylphosphine)palladium(II), dichlorobis(triphenylphosphine)palladium(II), or phenyliodobis(triphenylphosphine)palladium(II).The reactions are highly selective in that only the alkynyl groups are transferred from the stannane.
