Opening of the three-membered ring of spiro[2.4]hepta-4,6-diene ( 1 ) by Fe 2 (CO) 9 and CO insertion leads to the bridged η 1 -acyl-η 5 -cyclopentadienyl complex 3 , which with additional Fe 2 (CO) 9 via the labile intermediate 6 forms the dinuclear methylfulvene complex 4 ...
Uumlbergangsmetallfreie ReaktionenA practical method for ring opening of various indoles and benzofurans with concomitant stereoselective silylation using read‐ily generated (diphenyl‐tert‐butylsilyl)lithium to provide ortho‐β‐silylvinyl anilines or phenols is presented. Dearomatization of the ...
