Formation and efficient addition of cerium(III) derivative of acetonitrile to ketones
摘要:
The cerium(III) derivative of acetonitrile undergoes addition with ketones efficiently. It adds effectively to hindered ketones and gives 1,2-adduct exclusively with conjugated enones.
Zirconocene(iso-butyl) chloride: In situ generation of a zirconocene(methyl) chloride equivalent for use in organic synthesis
摘要:
Zirconocene(iso-butyl) chloride, 1, which can be generated in situ from commercially available, inexpensive, and air-stable zirconocene dichloride, can function as a zirconocene(methyl) chloride equivalent.
