GOLD-CATALYSED PROCESS FOR MANUFACTURING CHROMENES INTENDED FOR THE PREPARATION OF THERMOSETTING RESINS

A process for manufacturing chromenes intended for the preparation of thermosetting resins, includes transforming an aromatic propargyl ether of general formula (I) into a chromene by homogeneous gold(I) catalysis with the catalyst (acetonitrile)[(2-biphe

PROCESS FOR PRODUCING CHROMENES BY CATALYSIS WITH COPPER SALTS INTENDED FOR THE PREPARATION OF THERMOSETTING RESINS

A process for producing chromenes intended for the preparation of thermosetting resins, includes converting an aromatic propargyl ether of general formula (I) into a chromene by homogeneous catalysis with copper salts in anisole at a temperature between 1

Low-valent titanium mediated synthesis of hydroxystilbenoids: Some new observations

A series of phenolic stilbenoids possessing different numbers and positions of hydroxylation, partial methoxyl substituents and nature of olefinic moieties has been synthesized by McMurry coupling. It is found that the McMurry coupling of the phenolic aldehydes furnishes the dihydrostilbenes via an in situ hydrogenation, while the phenolic ketones give the stilbenes. Interestingly, the study also reveals that the low-valent titanium reagent (TiCl 3-Zn-THF) could selectively depyranylate phenolic -OTHP function without affecting alcoholic -OTHP group.

Nucleophilicity and Basicity of Phenols in the Aminolysis of Corresponding Aryl Acetates with Piperidine

A correlation was found between the nucleophilicity and basicity of phenols in the aminolysis of corresponding aryl acetates with piperidine. The correlation is satisfactorily described by the Bronsted equation. The nucleophilicity of low-molecular-weight phenols and phenol oligomers of vegetable origin (lignins) was estimated.
