(E)-1-fluoro-4-(4-iodostyryl)benzene is an organic chemical compound characterized by a fluorinated benzene ring with a 4-iodostyryl group attached to the 4-position. This molecule features a fluorine atom at the 1-position and a 4-iodostyryl group, which consists of a vinyl group (C=C) connected to a 4-iodophenyl ring, at the 4-position of the benzene ring. The compound's structure is defined by the E-configuration, indicating the relative positions of the fluorine and iodine atoms on the double bond. (E)-1-fluoro-4-(4-iodostyryl)benzene may be of interest in the synthesis of more complex molecules, potentially in pharmaceutical or materials science applications, due to its unique combination of halogenated and unsaturated functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 38695-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,6,9 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 38695-37:
(7*3)+(6*8)+(5*6)+(4*9)+(3*5)+(2*3)+(1*7)=163
163 % 10 = 3
So 38695-37-3 is a valid CAS Registry Number.

Palladium-Catalysed Desulfitative Heck Reaction Tolerant to Aryl Carbon-Halogen Bonds for Access to (Poly)halo-Substituted Stilbene or Cinnamate Derivatives

Skhiri, Aymen,Salem, Ridha Ben,Soulé, Jean-Francois,Doucet, Henri

, p. 3097 - 3106 (2016)

The palladium-catalysed desulfitative Heck type reaction of (poly)halo-substituted benzenesulfonyl chlorides with alkenes was investigated. Styrene or acrylates in the presence of bromo- or iodobenzenesulfonyl chlorides and a phosphine-free palladium catalyst were found to afford the expected β-arylated Heck type products with complete regio- and stereoselectivities. The reaction tolerates a variety of substituents on the halobenzenesulfonyl chloride. Moreover, no cleavage of the C-Br and C-I bonds was observed in the course of these reactions, allowing further transformations. Using 4-bromobenzenesulfonyl chloride as the central unit, consecutive desulfitative Heck type reaction followed by palladium-catalysed direct arylation allowed to prepare heteroarylated stilbene derivatives in only two steps.
