Indeno[2,1-b]thiophene and indeno[1,2-b]indole motifs have been obtained in moderate to good yields from easily available substituted boronic acids, 2-bromo aryl/vinyl aldehydes, and nucleophiles such as arenes/heteroarenes and others using a catalytic co

An efficient and mild Fe(III)-catalyzed intramolecular Friedel-Crafts alkylation of biaryl methanol derivatives has been developed to achieve the substituted fluorene derivatives. The present reaction provides an excellent alternative to published methods
PHOTOCHEMICAL REACTIONS OF TRIARYLMETHYL PEROXIDES (II) α- AND β-NAPHTHYLDIPHENYLMETHYL PEROXIDE

The photochemical decomposition of the title compounds and isotopically labeled analogs have been compared to the thermal rections.Rapid radical 1,2-migration and reversible elimination of oxygen from the starting peroxides are indicated.

Equilibrium cesium ion pair acidities of acetophenone, propiophenone, isobutyrophenone, and o-methoxyacetophenone and the lithium ion pair acidity of o-methoxyacetophenone in tetrahydrofuran have been determined by an indicator method.For all of these compounds, the observed pKa values decrease as the equilibrium enolate concentration is increased.It is proposed that this concentration dependence is a consequence of the aggregation of the enolates, and a method is described whereby average aggregation numbers can be determined from the acidity data.The results indicate that the extent of aggregation of enolate ions is influenced by both electronic and steric factors.In addition, internal solvation is found to be important for the lithium, but not the cesium enolate of o-methoxyacetophenone.
GENERATION AND THERMAL BOND RELOCATION OF A STERICALLY CONGESTED CYCLOTETRAENYL ANION
Anastassiou, A. G.,Kasmai, H. S.,Hasan, M.
, p. 1695 - 1698 (2007/10/02)
The sterically strained anion 4 was found to be thermally labile to subzero workup, readily undergoing temperature-dependent electrocyclization to a variety of tetracyclic frames.
