We investigated the ortho-alkylation of o-, m-, and p-cresols with cyclohexene in the presence of the corresponding aluminum cresolates in the range of 170-220/sup 0/C in an autoclave in an atmosphere of nitrogen at pressures of 1.0-1.5 MPa. The molar ratios of the cresolates, cyclohexene, and catalysts were varied in the ranges of 301:1-4:0.1-0.3, and the length of the experiment was varied in the range of 2-12 h. The highest selectivity is obtained during the alkylation of p-cresol. The reaction of o-, m-, and p-cresols with cyclohexene in the presence of the corresponding aluminium cresolates leads to mixtures of ethers and phenols, in which the ortho-alkylation products, formed with yields of 75-85%, predominate.
