(Z)-4-Heptenyl-triphenylphosphonium-bromid is a phosphonium salt with the chemical formula C23H26BrP. It is a colorless solid that is soluble in organic solvents. <(Z)-4-Heptenyl>-triphenylphosphonium-bromid is characterized by a (Z)-4-heptenyl group attached to a triphenylphosphonium cation, with a bromide anion. It is often used as a phase-transfer catalyst in organic synthesis, facilitating reactions between organic and inorganic compounds. The (Z)-4-heptenyl group provides steric and electronic properties that can influence the reactivity and selectivity of the catalyst.

6191-72-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6191-72-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,9 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6191-72:
(6*6)+(5*1)+(4*9)+(3*1)+(2*7)+(1*2)=96
96 % 10 = 6
So 6191-72-6 is a valid CAS Registry Number.

A Stereoconvergent Cyclopropanation Reaction of Styrenes

del Hoyo, Ana M.,Herraiz, Ana G.,Suero, Marcos G.

, p. 1610 - 1613 (2017/02/05)

The first stereoconvergent cyclopropanation reaction by means of photoredox catalysis using diiodomethane as the methylene source is described. This transformation exhibits broad functional group tolerance and it is characterized by an excellent stereocontrol en route to trans-cyclopropanes regardless of whether E- or Z-styrene substrates were utilized.
