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.
当R 1 = R 2 = R 3 = Me时,在R 1 R 2 C(SCH 2 C 6 H 5)CH 2 CH(R 3)OTs的甲醇分解中,经由四元环中间体的相邻基团参与导致完全重排。当R 1= R 2= Me时,R 3= H。对于R 1= R 2= R 3= H或R 1= R 2= H,R 3= Me ,没有发现重排。R 1 = Me,R 2的情况= R 3 = H是中间的。
