General Description

"(1-Ethynylcyclopropyl)benzene is an organic compound, a subset of hydrocarbons known as alkynes. The name denotes its chemical structure that includes an ethynyl group (C≡CH) and a cyclopropyl group (-C3H5), both attached to a benzene ring. The benzene ring, a significant component, is a six-membered carbon ring with alternating double bonds while the cyclopropyl group is a three-membered carbon ring and the ethynyl group comprises a carbon-carbon triple bond. Like many other organic compounds, careful handling is required due to the potential for chemical reactivity. However, detailed information about its toxicity, hazards, or uses is limited and further research may be needed to fully understand its characteristics and potential applications.

Check Digit Verification of cas no

The CAS Registry Mumber 139633-98-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,3 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139633-98:
(8*1)+(7*3)+(6*9)+(5*6)+(4*3)+(3*3)+(2*9)+(1*8)=160
160 % 10 = 0
So 139633-98-0 is a valid CAS Registry Number.

Biarylphosphonite gold(I) complexes as superior catalysts for oxidative cyclization of propynyl arenes into indan-2-ones

Henrion, Guilhem,Chavas, Thomas E. J.,Le Goff, Xavier,Gagosz, Fabien

supporting information, p. 6277 - 6282 (2013/07/11)

Striking gold: A series of variously functionalized propynyl arenes was smoothly converted into indan-2-ones by a new gold(I)-catalyzed oxidative cyclization process. [LAu]NTf2 (Tf=trifluoromethanesulfonyl) is a superior catalyst both in terms of yield and kinetics for the present transformation. Copyright

Nucleophilic substitutions of 1-alkenylcyclopropyl esters and 1-alkynylcyclopropyl chlorides catalyzed by palladium(0)

Stolle, Andreas,Ollivier, Jean,Piras, Pier Paolo,Salaün, Jacques,De Meijere, Armin

, p. 4051 - 4067 (2007/10/02)

The 1-ethenylcyclopropylsulfonates 2e,f and 2-cyclopropylideneethyl esters 10b,c, readily available from cyclopropanone hemiacetal 1, undergo regioselective Pd(0) catalyzed nucleophilic substitution via the unsymmetric 1,1-dimethylene-π-allyl complex 23. With stabilized anions (enolates of malonic ester, β-dicarbonyl compounds, β-sulfonyl ester, and Schiff bases as well as acetate anion, sulfonamide anion, etc.) the nucleophilic substitution occurs at the terminal vinylic position exclusively, providing cyclopropylideneethyl derivatives as building blocks of high synthetic potential. Competition experiments have disclosed that 1-ethenylcyclopropyl tosylate (2e) and cyclopropylideneethyl acetate (10b) are more reactive than dimethylallyl acetates 19 and 22, respectively. Use of chiral phosphines as ligands in the palladium catalyst can provide optically active methylenecyclopropane derivatives. With phenyl-, methyl-, and even n-butylzinc chloride as nucleophiles, the reaction apparently proceeds with initial transfer of the organic residue to palladium, followed by reductive elimination entailing tertiary substitution on the cyclopropane ring exclusively; the same type of product is obtained with azide and bis(trimethylsilyl)amide. But the site of hydride attack to yield reduction products depends on the hydride source. 1-Alkynylcyclopropyl chlorides 12, 13, and 14 react only with organozinc chlorides (nonstabilized nucleophiles) to provide mixtures of ethenylidenecyclopropanes 65 and alkynylcyclopropanes 66, via the σ-palladium complexes 69 and 70, while chloride 15 undergoes mainly reduction. Other transition metal catalysts (Ni, Mo) also induce substitutions, but with poorer regioselectivity.
