Reaction of p-anisidine 13 or p-bromo orthoanisidine 14 with the new bi-deuterated dienyl complex 12 bearing a leaving group on its side chain affords the mono-deuterated 18a, 19a and the non-deuterated lgb and 19b spiro[1,2,3,4-tetrahydroquinoline-4,1'-cyclohexane] derivatives. The formation of the
Chelated dicarbonyl 014-4-methoxycyclohcxadiene) iron complexes 6 and 15 which possess a phosphinilc and a phosphme bridge respectively form a new class of iron complexes.

The reaction of neutral 1-substituted-tricarbonyl(q4-4-methoxycyclohexa-l,3-diene)iron complexes 3 with thallium(III) trifluoroacetate in alcoholic solution leads to the corresponding new 4-substituted-tricarbonyl(q 4cyclohexa-2,4-dien-l-one)iron complexes 4. A mechanism for this reaction is propose
