摘要

disclosed cykloadduktu00f3w way receive dielsa - mccormack in response cykloaddycji dielsa - mccormack (model 1) and the corresponding dienu dienofilu (model 2) where: r - h, me, ome, r1 - c (o) c (o) ch3 och3, c (o) c (o) c2h5, oc2h5, ch3, h r2 - c (o) r3 - och3, h, ch3, h, r4 - cho, h, without the participation of the solvent.in the presence of a catalyst in the form of liquid chlorometalicznej heterogeneous ion immobilizowanej by cation via binding to kowalencyjnego silica structured micro - and makroporu00f3w, of general formula: sio2 - [tespmim] + [mxcly] - (model 3), where sio2, silica of the iniu0119tej structure of micro - and makroporu00f3w,[tespmim] + is the cation 1 - (3 - trietoksysilylopropylo) - 3 - [metyloimidazoliowy, mxcly] - anion chlorometaliczny, where m = aliii, gaiii, iniii, feiii, znii tiiii, tiiv, snii, sniv, where x = 1, y = 2, 3, 4, 7 or 10 different the mole fraction of metal in the structure of (? mclz in the range from 0.5 to 0.75), at a temperature of - 50 - 25 degrees celsius during the 5 - 360 minutes.
