The treatment of carbonyl compounds with the organotitanium species formed from methoxybis(phenylthio)methane and low valent titanium species Cp2Ti[P(OEt)3]2 gave 1-alkenyl ethers in good yields. 1-Alkenyl sulfides were also obtained by the similar reaction using triphenyl trithioorthoformate. These reactions were successfully applied to carboxylic esters and thiolesters to produce 1,2-diheteroatom
