Answer to Question #164822 in Organic Chemistry for Mary

Question

Na[W(η 5 -C5H5)(CO)3] reacts with 3-chloroprop-1-ene to give a solid, A, which has the molecular formula [W(C3H5)(C5H5)(CO)3]. Compound A loses carbon monoxide on exposure to light and forms compound B, which has the formula [W(C3H5)(C5H5)(CO)2]. Treating compound A with hydrogen chloride and then potassium hexafluorophosphate, K+PF6 − , results in the formation of a salt, C. Compound C has the molecular formula [W(C3H6)(C5H5)(CO)3]PF6. Use this information and the 18-electron rule to identify the compounds A, B, and C. Sketch a structure for each, paying particular attention to the hapticity of the hydrocarbons.
