O-sulfinylation with methanesulfonyl cyanide or p-toluenesulfonyl cyanide and DBU.
摘要:
Reaction of methanesulfonyl cyanide or p-toluenesulfonyl cyanide with alcohols in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) gives sulfinates in good yield. A mechanistic scheme involving sulfinyl cyanates is suggested.

Reaction of p-toluenesulfonyl cyanide or methanesulfonyl cyanide with alcohols in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) or 1,4-diazabicyclo[2.2.2]octane (DABCO) gives sulfinates in good yield. A mechanistic scheme involving sulfinyl cyanates 9 and 21 is suggested.
