The organotitanium sigma complex produced by the reaction of lithium derivatives of allyl phenyl ether with (i-PrO)/sub 3/TiCl reacts with aldehydes and ketones, forming ..cap alpha..-regioisomeric condensation products with high selectivity. In the case of the organotitanium derivatives of ..gamma..-substituted allyl phenyl ethers the ..gamma..-regioisomeric products are formed. The effect of the nature of the carbonyl compound and the allyl phenyl ether on the stereoselectivity of condensation is studied.
