• such an extent, that no new maximum representing the cis-isomer was observed and thus cis–trans isomerization only occurs thermally and is not triggerable by irradiation with visible light. Back-isomerization was triggered by irradiation with visible light (5a, 5b, 16a, 16b, 23, and 28) of the

Keywords: acid; activation by acid; metathesis; polymer; quinolin; ruthenium; triggerable; Introduction The modulation of the activity of enzymes by chemical triggers, e.g., by allosteric binding is ubiquitous in

• extension polymers, as well. Olefin metathesis polymerizations are transition metal-mediated processes which emerged as powerful alternatives to these conventional polymerization methods [22][23]. Thus, it is not surprising that a series of latent but triggerable initiators have been disclosed in the last

• active species. Another excellent example for nondirect activation of metathesis is the light-triggerable liquid-filled solid microcapsules (MCs) presented by Fréchet et al. in 2009 [80]. A solution of 39 in toluene inside macrocapsules (Figure 14) can stand for weeks in neat DCPD without any appreciable
