  coordination complexes toward heterocumulenes, such as carbodiimides, isocyanates, and isothiocyanates is reported. The mono(imidazolin‐2‐iminato) thorium(IV) complex [Th(ImDippN)N(SiMe3)2}3] (1) was applied as a precatalyst for the addition of EH (E=N, P, S) bonds to the YCX core (Y=R2N; X=NR2, O, S) of carbodiimides, isocyanates, and isothiocyanates. The respective insertion products were obtained

  据报道，act系配位络合物对杂碳烯，如碳二亚胺，异氰酸酯和异硫氰酸酯的催化活性前所未有。单（咪唑啉-2-亚氨基））（IV）络合物[Th（Im Dipp N）N（SiMe 3）2 } 3 ]（1）被用作添加EH（E = N ，P，S）键合至碳二亚胺，异氰酸酯和异硫氰酸酯的YCX核（Y ＝ R 2 N； X ＝ NR 2，O，S）。各个插入产物在温和的反应条件下以高收率获得，其中配合物1显示出对官能团和杂原子的高耐受性。

  A welding accessory and a system for detecting thermal and/or UV radiation exposure during welding operations are disclosed. The welding accessory may have a surface exposed to thermal and/or UV radiation generated by electric arc welding, a first image visible without exposure to the thermal and/or UV radiation, and a second image formed from either a UV activated dye that is visible only after exposure to UV radiation generated by the electric welding arc or a thermochromic dye that is visible only after exposure to a predetermined level of thermal radiation generated by the welding arc. A system may include either a thermal or UV exposure indicator with a first state and at least a second state, and include either a thermochromic or UV activated dye adapted to provide a reversible or persistent visual indication upon exposure to radiation. The visual indication may include any combination of symbols, logos, images, text, or other decorative or informational designs as desired.
