Method for obtaining the Diels-Adler cycloadducts

摘要

the object of the application is the way for cykloadduktów dielsa - mccormack of dienu of general formula 1 and dienofilu of general formula 2 is,that these compounds is replaced in the atmosphere gas inertnego, without solventin the presence of 5 to 20 mole% of liquid metal complexes as catalysts of the following general formula mclx - l - y, where l is a ligand: urea (ur), thiourea (sur), trioktylofosfina (p888)trioctylphosphine oxide (p888o), dimethylacetamide (dma), where m = aliii, gaiii, iniii, feiii, znii, tiiii, tiiv, snii, sniv, sbiii, where x = 2, 3 or 4,where y is the share of metal chloride in molar structure? mclx = 0.50, 0.60, 0.67 or 0.75, reaction is in the temperature range from - 50 to - 25 degrees celsius during 5 - 360 minutes.
