Abstract

The diyne 4,7,10-trithiatrideca-2,11-diyne (TTDD) reacts smoothly at room temperature with [Ru(CO)2(PPh3)3] to form [Ru(CO)(PPh3){4-S(C2H4SCCMe)2CO-S}], a cyclopentadienone complex in which the unique sulfur atom is also coordinated to the metal but may be displaced by dppe to provide [Ru(CO)(dppe){4-S(C2H4SCCMe)2CO}]. In contrast, 2,8-decadiyne fails to cyclize even at elevated temperatures, implicating thioether coordination in the mechanism of TTDD macrocyclization.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
