Double-coupling of dibromo arenes with aryltriolborates for synthesis of diaryl-substituted planar frameworks

A new method for simple and practical synthesis of diaryl-substituted arenes using potassium aryltriolborates was developed. Double-cross-coupling of dibromo arenes with aryltriolborates was carried out in the presence of a palladium catalyst, such as Pd(

Preorganized Bis-ethynes: Molecular ?-Tweezers?

1,8-Bisnaphthalenes of tyle V ( e.g. 10,11) and 1,8-bisnaphthalenes (6,6a,7,7a) were synthesized for the first time .In contrast to the known 1,8-bis(arylethynyl)naphthalenes VI their "stereologs" 10 and 11 are thermally stabile.Yet they react with pentacarbonyliron to yield dinuclear transition metal complexes of the type 12, 13, i.e. a strained cyclophane macrocycle is formed by C-C bond formation.The X-ray analysis of the di-tert-butyl compound 11 shows that the peri substituents diverge, but with increasing distance from the naphthalene skeleton one of the arylethynyl units is bent to the opposite direction (Figure 2).The question whether the new molecular skeleton V can be viewed as molekular tweezers is discussed: as the hydrocarbons react irreversibly with transition metal carbonyls, they may rather be taken as "tweezers for single use".

Desing and Synthesis of New Acidic EDTA-Type Complex Ligands

The terminus "stereology" is defined in the sense of a spatially more or less analogous arrangement - referred to a mother substance - of two or more molecular parts relative to each other.The concept developed therefrom is explained using examples.It can be applied for the desing of new compound families in different fields of chemistry.This is experimentally established with novel acidic complexones of the EDTA-type.The stability constants measured potentiometrically between the EDTA-stereologous bis(aminediacetic acids) 2d, 6d, 8d and alkaline earth metal cations are discussed especially with respect to a cooperative donor engagement.
