- A sulfonium ion (R3S+) is a stereogenic center if three different alkyl groups are bonded to sulfur because sulfur is surrounded by four different groups, including its lone pair. In assigning an R or S) is a stereogenic center if three different alkyl groups are bonded to sulfur because sulfur is surrounded by four different groups, including its lone pair. In assigning an designation to sulfur, the lone pair is always assigned the lowest priority (4). SAM, S -adenosylmethionine, is a biologically active sulfonium ion that we will learn about in Section 7.16. Locate all the stereogenic centers in SAM, and assign an R,S designation to each center.Rank the following groups in order of decreasing priority. −C≡CH, −CH(CH3)2, −CH2CH3, −CH=CH2Draw the products formed when hex-1-yne is treated with each reagent. a.
