Linked from

The 14 pages that link to Pyrrole, each with the reason it gives.

• Heterocyclic compoundBroader topic: Its nitrogen lone pair contributes to aromaticity, making it much less basic than pyridine.

• PyridineCompared with: Unlike pyridine, pyrrole uses its nitrogen lone pair as part of the aromatic sextet.

• Aromatic compoundBroader topic: Pyrrole illustrates a heteroatom lone pair becoming part of the aromatic electron count.

• PorphyrinBroader topic: Four pyrrole-derived units form the characteristic porphyrin framework.

• IndoleRelated: The pyrrole ring supplies indole’s nitrogen and one half of its fused scaffold.

• FuranRelated: Pyrrole is a close ring analogue with nitrogen where furan has oxygen.

• ImidazoleCompared with: Pyrrole shows how replacing one imidazole nitrogen changes basicity and electron donation.

• ThiopheneCompared with: Pyrrole is a close ring analogue with nitrogen instead of sulfur.

• Hans FischerRelated: Pyrrole units form the ring framework of the pigments Fischer investigated.

• PyrrolidineCompared with: Pyrrole has the same ring size but is unsaturated and aromatic.

• CarbazoleBroader topic: Its nitrogen-containing ring is the central component of carbazole’s fused framework.

• BiliverdinBroader topic: Four pyrrole-derived units form the backbone of biliverdin.

• IsoxazoleCompared with: Pyrrole has one ring heteroatom rather than adjacent oxygen and nitrogen.

• PyrazoleRelated: Comparing its single nitrogen with pyrazole’s two clarifies ring aromaticity.
