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

Ninhydrin and related indanone scaffolds are employed as effective synthon in organic bioorganic chemistry. In the present work, reactivity of ninhydrin is exploited to synthesize various cyclic acyclic compounds using mortar pestle grinding method. The reaction with naphthols, phenols, acetylacetone/ethylacetoacetate under condition led fused/spirocyclic products. On other hand, 2-methoxynaphthalene, 4-hydroxycoumarin, 1,3-indanedione, indole reacted afford simple C-2 arylated adducts. Single crystal X-ray diffraction study revealed that, ninhydrin-o-cresol adduct, which preferentially remains hemiketal form 6, self-assembled adopt zipper architecture. However, ninhydrin-2-methoxynaphthalene adduct 7 was found display corrugated sheet like arrangement. Scanning electron microscopy (SEM) reveals that adducts 8, 10 exhibit fibrillar morphology, whereas 7, 12, 15 disclose morphology.
