    • 2 (1.5 mmol) and LiCl (3 mmol) in 50 ml of THF was stirred at room temperature until complete dissolution of the salts. A THF solution of HeptMgCl (1.5 M, 50 mmol) was then added in 30 min. at 0–10°C.It is advised to introduce the Grignard with a mechanical pump to control efficiently the addition rate. The reaction mixture was then stirred for 10 min. and the ketone BuCOHept was isolated by distillation after a usual work-up (1M HCl hydrolysis).

    • It is already known that, in some cases, the acylation of RMnCl in THF gives better yields in the presence of a catalytic amount of copper chloride (see ref. 3).

    • We have verified that this result cannot be obtained in the presence of copper (I or II) chloride alone.
