Abstract
A new catalytic reaction - dimerization of acetylene accompanied by ad dition of iodine to yield (E,E)-1,4-diiodobuta-1,3-diene at 30 degrees C in a methanolic solution of NaI, Pt-IV and I-2 - has been found; a plausible reaction mechanism involves intermediate formation of a cis- divinyl derivative of platinum(IV) through two subsequent triple bond iodoplatination steps followed by reductive elimination of the final p roduct.
