A series of three-component heterogeneous catalysts Au—Ch—SiO2 with Ch for chitosan was prepared. The size of gold nanoparticles immobilized on the chitosan matrix depends on the method of sample preparation. The particles with the size <3 nm are formed when the preliminary prepared homogeneous Au—Ch complex is supported on SiO2. The catalysts were tested in the intramolecular cyclization reaction of 2-(2-phenylethynyl)aniline to for 2-phenylindole. The maximum conversion of 2-(2-phenylethynyl)aniline (25% within 35 h) was obtained on the Au(0.4%)—Ch(2.9%)/SiO2 catalyst.
