Abstract:

Condensation of the formyl group of Cp3Fe4(CO)4(C5H4CHO) with N-methylglycine and C60 produces Cp3Fe4(CO)4(C5H4-CHNMeCH2C60) (1), where one cyclopentadienyl ring of the tetrairon cluster is linked to a fulleropyrrolidinyl moiety. A similar reaction with the bisformyl cluster Cp2Fe4(CO)4(C5H4CHO)2 affords Cp2Fe4(CO)4(C5H4-CHNMeCH2C60)2 (2). Compounds 1 and 2 have been characterized by mass, IR, UV-Vis, and NMR spectroscopy. The electrochemistry of 1 and 2 was investigated by cyclic voltammetry and differential pulse voltammetry.

Cycloaddition Reactions: MO Requirements for Thermal Activation

Thermal cycloadditions are reactions where the source of activation energy needed to initiate the reaction is provided in the form of heat. A typical example of a thermally-allowed cycloaddition is the Diels–Alder reaction, which is a [4 + 2] cycloaddition. In contrast, a [2 + 2] cycloaddition is thermally forbidden.

Five-Membered Heterocyclic Aromatic Compounds: Overview

Five-Membered Heterocyclic Aromatic Compounds: Overview

Heterocyclic aromatic compounds are cyclic compounds that are aromatic and have one or more heteroatoms—atoms other than carbon, in the ring. Depending upon the number of atoms present in the ring, they can be either five or six-membered. Examples of five-membered heterocyclic aromatic compounds include pyrrole, furan, thiophene, and imidazole. Pyrrole consists of one nitrogen atom having one lone pair of electrons. Furan and thiophene have one oxygen and one sulfur heteroatom, respectively.
