Synthesis and molecular structure of MnW-carbonyl complex with bridge product of isomerization of monothiolatsubstituted butenediol

Complex with monohydroxymonothiolatesubstituted acetylene which transforms in heterometallic complex CpMn(CO)2[CH2=CH(CO)CH2SCMe3]W(CO)4 by reaction with W(CO)5 · THF is prepared by reaction CpMn(CO)2[C2(CH2OH)2] with tret-BuSH in the presence of aqueous HBF4. On x-ray structural analysis data substitution of one OH group for tret-butylthiolate residue and acetylene isomerization in vinylketothiolate hydrocarbon occur in the complex. Manganese atom is in coordination with appeared end double bond C=C and tungsten atom is chelated by sulfur atom of thiolate group and by oxygen atom of ketone group with formation of five-membered intramolecular cycle
