Conclusions
-
1.
Reductive coupling of butyryl chloride with CoCl(PPh3)3 affords 4-heptanone, 4,5-octanedione, 4-hydroxy-5-octanone, 4-butyryloxy-5-octanone, and 4,5-dibutyryloxy-4-octene.
-
2.
A mechanism for the reductive coupling of butyryl chloride is proposed, involving the intermediate formation of an acylcobalt(III) dichloride complex.
