ring opening उदाहरण वाक्य

A 4n + 2 electrocyclic ring opening reaction is also a 2-component pericyclic reaction which is suprafacial with respect to the ?-system.
Being a basic alkoxide, Al ( O-i-Pr ) 3 has been also investigated as a catalyst for ring opening polymerization of cyclic esters.

"' Polydicyclopentadiene "'( PDCPD ) is a polymer which is formed through ring opening metathesis polymerisation ( ROMP ) of dicyclopentadiene ( DCPD ).
The product formed is an imidazolin-4-one which can be either isolated as a diastereomers or be used to give a Schiff base via ring opening.

Chloroiodomethane is used in cyclopropanation ( " Simmon-Smith reaction " ), Mannich reaction, aminomethylation, epoxidation, ring opening and addition to terminal alkenes.
Polyesters can be synthesized in a number of ways including direct condensation of alcohols and acids, ring opening polymerizations ( ROP ), and metal-catalyzed polymerization reactions.
As most biodegradable polymers have been synthesized by ring opening polymerization, a thermodynamic equilibrium exists between the forward polymerization reaction and the reverse reaction that results in monomer formation.
In the conrotatory ring opening of cyclobutene, there are two electrons moving suprafacially ( on the pi bond ) and two moving antarafacially ( on the sigma bond ).
For the photoinduced ring opening of cyclobutene, is it shown that the disrotatory motion predicted by the Woodward Hoffmann rules is established within the first 50 fs after optical excitation.
