(Alkynylcyclobutadiene)tricarbonyliron: new organometallic alkynes
摘要:
Treatment of (iodocyclobutadiene)tricarbonyliron (1a) with different stannylated alkynes under the conditions of Stille coupling gives the corresponding alkynylated complexes in 35-69% yields. A dinuclear (1,2-bis[(cyclobutadiene)tricarbonyliron]ethyne) and a heterometallic trimeric complex are also obtained by this route. Stannylated butadiynes also couple readily with 1a to the corresponding (cyclobutadiene)tricarbonyliron-substituted diynes.
