Sodium hydrideCα -Permethylation may be carried out by addition of a basesensitive ketone like cyclopentanone to the inexpensive and stable mixture of sodium hydride and dimethyl sulfate. Exhaustive C α -ethylation is exemplified with sodium hydride by simultaneous introduction of ketone 4 and ...
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 ...
