- 中文摘要:
A study of the regioselectivity in nucleophilic addition to tricarbonyl (dienylium) iron complexes having an acetoxyethyl group (or methoxyethyl group) is reported. Reaction of the acetoxyethyl dienylium complex with the potassium salt of methyl 2-oxocylopentanecarboxylate was found to give a new product and a mechanism is proposed.
The regioselectivity to nucleophilic addition was shown to be dependent on the use of an alcohol protecting group as in tricarbonyl (dienylium) iron complexes (5) and (15). - 英文摘要: --
