Check Digit Verification of cas no

The CAS Registry Mumber 1460-02-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,6 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1460-02:
(6*1)+(5*4)+(4*6)+(3*0)+(2*0)+(1*2)=52
52 % 10 = 2
So 1460-02-2 is a valid CAS Registry Number.

Carbon dioxide promoted palladium-catalyzed cyclotrimerization of alkynes in water

Li, Jin-Heng,Xie, Ye-Xiang

, p. 1737 - 1743 (2004)

In water, CO2 was found to promote the palladium-catalyzed cyclotrimerization of alkynes. In the presence of PdCl2, CuCl 2, and CO2, both aryl and alkylalkynes afforded the corresponding cyclotrimerization products regioselectively in high yields. However, tert-butylacetylene bearing a bulk group gave a dimerization product.

Synthesis, crystal structure, and nonlinear optical behavior of β-unsubstituted meso-meso E-vinylene-linked porphyrin dimers

Frampton, Michael J.,Akdas, Huriye,Cowley, Andrew R.,Rogers, Joy E.,Slagle, Jonathan E.,Fleitz, Paul A.,Drobizhev, Mikhail,Rebane, Aleksander,Anderson, Harry L.

, p. 5365 - 5368 (2005)

(Chemical Equation Presented) A vinylene-linked porphyrin dimer, with no substituents at the β-positions, has been synthesized by CuI/CsF promoted Stille coupling. In the crystal structure of this dimer, the C2H 2 bridge is twisted by 45° relative to the plane of the porphyrins. The absorption, emission spectra, and electrochemistry reveal substantial porphyrin-porphyrin π-conjugation. The triplet excited-state absorption spectrum of this dimer makes it suitable for reverse saturable absorption at 710-900 nm.

Photoredox catalysis on unactivated substrates with strongly reducing iridium photosensitizers

Shon, Jong-Hwa,Kim, Dooyoung,Rathnayake, Manjula D.,Sittel, Steven,Weaver, Jimmie,Teets, Thomas S.

, p. 4069 - 4078 (2021/04/06)

Photoredox catalysis has emerged as a powerful strategy in synthetic organic chemistry, but substrates that are difficult to reduce either require complex reaction conditions or are not amenable at all to photoredox transformations. In this work, we show that strong bis-cyclometalated iridium photoreductants with electron-rich β-diketiminate (NacNac) ancillary ligands enable high-yielding photoredox transformations of challenging substrates with very simple reaction conditions that require only a single sacrificial reagent. Using blue or green visible-light activation we demonstrate a variety of reactions, which include hydrodehalogenation, cyclization, intramolecular radical addition, and prenylationviaradical-mediated pathways, with optimized conditions that only require the photocatalyst and a sacrificial reductant/hydrogen atom donor. Many of these reactions involve organobromide and organochloride substrates which in the past have had limited utility in photoredox catalysis. This work paves the way for the continued expansion of the substrate scope in photoredox catalysis.

Linear Hydroaminoalkylation Products from Alkyl-Substituted Alkenes

Warsitz, Michael,Doye, Sven

supporting information, p. 15121 - 15125 (2020/10/23)

The regioselective conversion of alkyl-substituted alkenes into linear hydroaminoalkylation products represents a strongly desirable synthetic transformation. In particular, such conversions of N-methylamine derivatives are of great scientific interest, because they would give direct access to important amines with unbranched alkyl chains. Herein, we present a new one-pot procedure that includes an initial alkene hydroaminoalkylation with an α-silylated amine substrate and a subsequent protodesilylation reaction that delivers linear hydroaminoalkylation products with high selectivity from simple alkyl-substituted alkenes. For that purpose, new titanium catalysts have been developed, which are able to activate the α-C?H bond of more challenging α-silylated amine substrates. In addition, a direct relationship between the ligand structure of the new catalysts and the obtained regioselectivity is described.

Generation of Alkyl Radical through Direct Excitation of Boracene-Based Alkylborate

Hashizume, Daisuke,Hosoya, Takamitsu,Nakamura, Kei,Ohmiya, Hirohisa,Sato, Yukiya,Sumida, Yuto

supporting information, p. 9938 - 9943 (2020/06/27)

The generation of tertiary, secondary, and primary alkyl radicals has been achieved by the direct visible-light excitation of a boracene-based alkylborate. This system is based on the photophysical properties of the organoboron molecule. The protocol is applicable to decyanoalkylation, Giese addition, and nickel-catalyzed carbon-carbon bond formations such as alkyl-aryl cross-coupling or vicinal alkylarylation of alkenes, enabling the introduction of various C(sp3) fragments to organic molecules.
