In this Communication, procedures for the selective synthesis of 4-arylbutanoic acids, 2-arylbutanoic acids, and 4-arylbutanals from the same allylbenzenes have been developed. With formic acid or TFBen as the CO surrogate, reactions proceed selectively and effectively under carbon monoxide gas-free conditions.

Zirconium and hafnium ansa-complexes containing 2,4,6-trialkyl-substituted indenyl fragments were synthesized and unambiguously characterized. Mixtures of rac- and meso-Me2Si(2-Me-4,6-R2C9H 3-η5)2MCl2, where R = Me, i-Pr and M = Zr, Hf, were obtained by a treatment of MCl4 by dilithium salts of the respective bis(2,4,6-trialkylindenyl)dimethylsilanes in toluene. Alternatively, better yields of the same complexes can be obtained by the reaction between metal tetrachlorides and indenyl-tin derivatives gave the desired ansa-metallocenes. All rac- and meso-complexes of Zr and Hf were isolated in an analytically pure form, and six of these ansa-metallocenes were characterized by X-ray crystal structure analysis.

Methyl derivatives of indan-1-one were prepared as models to aid in interpreting the carbon-13 nuclear magnetic resonance ((13)C-NMR) spectra of pterosin-sesquiterpenes which were isolated from bracken fern, Pteridium aquilinum var. latiusculum.The chemical shifts of the carbons of the methylindan-1-ones were assigned by the proton decoupling technique.All the (13)C-NMR signals of the pterosin-sesquiterpenes were assigned by means of selective proton decouplings, and from the (13)C-(1)H long-range couplings and (13)C chemical shifts of the model compounds.Keywords - indan-1-one derivative; methylindan-1-one; pterosin-sesquiterpene; methylindan-1-one synthesis; (1)H-NMR; (13)C-NMR; selective decoupling; C-H decoupling
