Syn-addition in organic chemistry happens when certain factors do not allow one of the reactants to rotate as an intermediate. Before the reaction starts, the site where the addition occurs is locked in place due to its pi-bond holding the structure in place. The first step of an addition...

Explain the advantages of using Pyridium tribromide over liquid bromine in an addition reaction for the bromination of stilbene. Explain the difference between (E)-stilbene and (Z)-stilbene. What is the difference between computational chemistry and computer s...
(organic chemistry) In stereochemistry, on the same side of a reference plane; for example, the stereochemical outcome of an addition reaction where the new bonds are on the same side of the original pi bond is called syn addition.
ZnI2 was found to be both very active and highly selective giving only E adducts through a syn addition. Scope and limits investigation showed that this catalyst was compatible with various functional groups. In addition to 17 examples of ynamide hydroalkoxylation, one example of ynamide hydro...
In addition, the isomers 2a-b and 3a-b could be also produced through the reaction of (eta(5)-RC5H4)(2)M-2(CO)(4) (M = Mo, R = MeCO, MeO2C) with Ph2Se2 in the solid state at cu. 110 degrees C in comparable total yields, but with a much higher isomer ratio (trans/sy...

The reaction can tolerate aryl and aliphatic groups at the α-position of VCPs, while VCP substrates with vinyl or alkynyl substitutions are not suitable ones. In addition, this reaction can also be used to synthesize bicyclic rings if an aryl group is attached to the vinyl......
