Palmieri, Alessandro et al. published their research in Synlett in 2008 | CAS: 10297-05-9

1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.SDS of cas: 10297-05-9

Double functionalization of N-Boc-3-(tosylmethyl)indole exploiting the activating properties of the tosyl group was written by Palmieri, Alessandro;Petrini, Marino;Shaikh, Rafik R.. And the article was included in Synlett in 2008.SDS of cas: 10297-05-9 This article mentions the following:

The anion prepared from N-Boc-3-(tosylmethyl)indole using NaH in DMF can be readily functionalized by reaction with various electrophiles. The obtained sulfonyl indoles, upon removal of the N-protecting group, undergo nucleophilic attack via a vinylogous imino derivative, leading to branched 3-substituted indoles. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9SDS of cas: 10297-05-9).
