“…A new type of coupling reagent for palladium‐catalyzed reactions was developed by Liebeskind and co‐workers towards the end of the 1990s:27 They employ various organosulfur compounds, and thiols or thioethers act as leaving groups. As sulfur in low oxidation states generally coordinates well to palladium and thus blocks free coordination sites, the corresponding sulfur compounds must be trapped or their complexation ability restricted to enable palladium‐catalyzed coupling reactions.…”

“…Eine neue Klasse von Kupplungsreagentien für Palladium‐katalysierte Reaktionen wird seit Ende der 1990er Jahre27 von Liebeskind und Mitarbeitern untersucht: Sie setzen verschiedene Organoschwefelverbindungen ein, bei denen Thiolate oder Thioether als Abgangsgruppen fungieren. Da die meisten Schwefelverbindungen in niedrigen Oxidationsstufen gut an Palladiumzentren koordinieren und dadurch freie Koordinationsstellen blockieren, müssen sie in ihrer Koordinationsfähigkeit eingeschränkt oder abgefangen werden.…”

“…( 1) and ( 2)) [2]. Whereas the benzylic thioether substrate is quite unreactive under these conditions [3], the discovery of the nickel-catalyzed cross coupling reaction of benzylic or allylic dithioacetals with Grignard reagents has paved a new route for the olefination of a carbonyl equivalent [4]. Representative examples are shown in Scheme 1 [4][5][6][7][8].…”
