SULFUR PARTICIPATION IN SOLVOLYSIS INVOLVING FOUR-MEMBERED RING INTERMEDIATES

Eliel, Ernest L.,Pearson, William H.,Jewell, Linda M.,Abatjoglou, Anthony C.,Kenan, William R.

, p. 331 - 334 (2007/10/02)

Neighboring group participation via four-membered ring intermediates resulting in complete rearrangement occurs in the methanolysis of R1R2C(SCH2C6H5)CH2CH(R3)OTs when R1=R2=R3=Me and when R1=R2=Me, R3=H.No rearrangement is found for R1=R2=R3=H or R1=R2=H, R3=Me.The case of R1=Me, R2=R3=H is intermediate.
