Introduction The oxidative cross-dehydrogenative coupling (CDC) reaction has emerged rapidly as one of the most straightforward and atom-economical strategies for forming C–C bonds through the direct coupling of two C(sp3)–H bonds, as it does not require additional prefunctionalization of substrates, and thus largely reduces the number …

Stereoselective β-C(sp 2)–H alkylation of enamides with redox-active N-hydroxyphthalimide esters via a photoredox-catalyzed decarboxylative cross-coupling reaction is demonstrated. This methodology features operational simplicity, broad substrate scopes, and excellent stereoselectivities and functional group tolerance, affording a …

Since tan(n) has a transcendental period, namely Pi, it seems very likely that not only tan(n) > n for infinitely many integers n, but also that tan(n) > kn for infinitely many integers n, for any integer k. It even seems likely that not only n < tan(n) < n+1 for infinitely many integers n (not just for n = 1), but also that kn < tan(n) < kn ...
