Reactive Intermediates
In chemistry, reactive intermediates are termed as short-lived, highly reactive atoms with high energy. They rapidly transform into stable particles during a chemical reaction. In specific cases, by means of matrix isolation and at low-temperature reacti…
Hydride Shift
A hydride shift is a rearrangement of a hydrogen atom in a carbocation that occurs to make the molecule more stable. In organic chemistry, rearrangement of the carbocation is very easily seen. This rearrangement can be because of the movement of a carboc…
Vinylic Carbocation
A carbocation where the positive charge is on the alkene carbon is known as the vinyl carbocation or vinyl cation. The empirical formula for vinyl cation is C2H3+. In the vinyl carbocation, the positive charge is on the carbon atom with the double bond t…
Cycloheptatrienyl Cation
It is an aromatic carbocation having a general formula, [C7 H7]+. It is also known as the aromatic tropylium ion. Its name is derived from the molecule tropine, which is a seven membered carbon atom ring. Cycloheptatriene or tropylidene was first synthes…
Stability of Vinyl Carbocation
Carbocations are positively charged carbon atoms. It is also known as a carbonium ion.

Interpretation Introduction

Interpretation: The product of the given reaction with mechanism is to be interpreted.

Concept introduction: The ring opening reaction of epoxide with base nucleophile proceeds through the SN2 mechanism. The strong nucleophile like NaOH leads to ring opening, whereas with weak nucleophile, the ring opening cannot possible.

Students have asked these similar questions
please draw detailed mechanism. mention which one is the nucleophile, electrophile,base/ acid. Also talk about stereochemistry/ regioselectivity. In terms of stereochemistry why are we getting trans alkene. Why is the trans alkene Produced is it due choosing PPh2 as regeant? Also This reaction is the Horner wadsworth emmond wittig.
What is an appropriate multi-step method/mechanism for the transformation shown in the image?? (One of the steps involved here can also be found at the end of Baylis Hillman and Rauhut-currier reactions. The red&green dots show where C from the beginning is now found in the end product.)
a) Show a detailed mechanism for the reaction to produce nitrogen gas and the two carbon radicals shown above.b) Show how the carbon radical produced above could react with HBr to make a bromine radical, completing the initiation step for the reaction at the top of the page.c) Show a detailed mechanism for the propagation step of the reaction at the top of the page and circle the major organic product produced from the reaction.
