Reaction of NaCO(CO)4 with R2BI under carbon monoxide at atmospheric pressure at room temperature readily gives the dialkyl ketones in good yields (61–85%) after H2O2/OH− oxidation.

Hydroboration of alkenes with sodium acetoxyborohydride(NaBH3OAc) followed by carbenoidation using NaOCH3/CHCl3 system and oxidation with H2O2/NaOH give dialkylketones.

Low molecular-weight derivatives obtained during ring-opening polymerization of norbornene using W(CO)3Cl2(AsPh3)2 as catalyst indicate that a 2,3-hydrogen shift is a key step for the formation of the carbene initiator.
