Two new m-acyl Fe-S complexes (m-R1S)(m-CH3CH:CHCO)Fe2(CO)6 (R1 = Et, tert-Bu) and three new m-alkenyl complexes (m-R1S)(m-CH3CH:CH)Fe2(CO)6 (R1 = Et, tert-Bu, CH2:CHCH2) have been synthesized by reactions of trans-crotonyl chloride with active intermediates [(m-CO)(m-R1S)Fe2(CO)6]- Et3N+H. The kinetics of CO extrusion reaction of m-acyl complexes to form m-alkenyl complexes has been investigated and showed that this type of reaction is first-order. The rate constants and half-life of the reactants have been calculated
