note
-
Treatment of thiol la with the catalyst R,R-A in dichloromethane or diethyl ether immediately precipitated a brown solid which was an active catalyst (see ref 12). Because of the lower solubility of this thiol complex, the reaction in dichloromethane or diethyl ether is less effective, leading to low yields and enantioselectivities.

The solid slowly liberates thiol at room temperature.

note
-
This complex was negative and positive in the halogen and sulfer tests, respectively, and no liberation of thiol Ia was detected. Although it is soluble in acetone, THF, and dichloromethane, no catalytic activity was observed in the thiol conjugate addition.
