65. Synthesis of Methylated, Hydroxylated, and Aminated Metallaaromatics viaRing-Opening Reactions of the Fused Three-Membered Ring Units

Abstract

The development of efficient functionalization methods for metallaaromatics is pivotal in manipulating their structural and chemical properties. While introducing hydroxyl and amino moieties into metallaaromatics is highly desirable, relevant reports remain scarce. In our approach, we exploit the reaction of hydroxylamine with a fused compound composed of a metallapentalene moiety and an unsaturated three-membered metallacycle. Upon exposure to air, hydroxylamine is oxidized by heating and forms a nitrosyl anion that replaces the chloride ligand within this system. The ligand exchange triggers the ring opening of the three-membered metallacycles, which is then followed by protonation, thereby generating a series of methylated, hydroxylated, and aminated metallaaromatic derivatives. This sequential process is accompanied by dearomatization and rearomatization within the metallapentalene frameworks, demonstrating the versatility of this new functionalization methodology.

Abstract

Utilizing rhodium complexes to catalyze 2‐vinylbenzaldehyde derivatives has proven to be a valuable strategy in constructing indanone moieties. In this study, the stoichiometric reactions of Wilkinson's catalyst RhCl(PPh3)3 with 2‐vinylbenzaldehyde derivatives were investigated, leading to the formation of rhodaindanone complexes (2). Notably, the transformation of of rhoda‐1‐indanone (2 a) to rhoda‐2‐indanone (3) was achieved for the first time. In comparision, the reactivity of IrCl(PPh3)3 and Ir(CO)(CH3CN)(PPh3)2 ⋅ BF4 towards 2‐vinylbenzaldehyde derivatives affords irida‐2‐indanone complexes (4) and fused iridacycles (5), respectively. These newly prepared coumpounds represent the first metellacycles resulting from the reactions between 2‐vinylbenzaldehyde derivatives and rhodium/iridium complexes and may provide further insights into the catalytic processes involving 2‐vinylbenzaldehyde derivatives for synthesizing indanone compounds.

Abstract

Comprehensive Summary: Metallacyclopentadienes are important metallacycles and regarded as intermediates in many reactions, therefore, new methods to achieve them are anticipated. In this study, a formal [3+2] method, through the reactions of an osmapentalyne with benzyl carbanions, was developed. The reactions underwent a nucleophilic attack of carbanions to the Os≡C bond, followed by C—H activation to form the five‐membered osmacyclopentadiene ring. Most of the reactions were carried out at room temperature, the substituents on the aromatic rings of benzyl carbanions are diverse, and the resulting products contain an Os—H bond, representing a novel type of 10C‐carbolong complexes. This work provides a new convenient route to construct metallacyclopentadienes, which is expected to further promote the development of such a type of substances. [ABSTRACT FROM AUTHOR]
