There is provided herein a method of preparing an isocyanatosilane including reacting an olefinic isocyanate with a hydridosilane in the presence of a dinuclear rhodium complex under hydro silylation conditions.
The challenging transamidation of unactivated tertiary amides using equivalent amounts of amines has been accomplished via cooperative acid/iodide catalysis. The method provides a novel manifold to re-route the reactivity of unactivated and unreactive N,N-dialkyl amides through reactive acyl iodide intermediates, representing a powerful new activation mode of unactivated amide bonds.

Disclosed are a crystalline polypropylene resin composition comprising a crystalline polyproplylene resin and a β-nucleating agent, and a method of increasing the proportion of β-form crystals in a crystalline polypropylene resin molding comprising molding the composition, the β-nucleating agent being a diamide compound.
There is provided herein a method of preparing an isocyanatosilane including reacting an olefinic isocyanate with a hydridosilane in the presence of a dinuclear rhodium complex under hydrosilylation conditions.
An ink composition comprising: a self-dispersing carbon black, a binder, a stabilizing dye comprising at least as many groups comprising CO
2
H or COSH as groups comprising SO
3
H, and an aqueous vehicle. The stabilizing dye can improve the reliability and performance of the ink composition. The addition of the stabilizing dye can reduce or prevent the formation of material that blocks the printhead vias and throats as a result of the presence of a binder in the ink. The ink composition can reduce the amount of maintenance needed to retain all of a printhead's nozzles through the life of the printhead.
一种墨水组合物,包括:一种自分散炭黑、一种粘合剂、一种稳定染料,该染料至少包含由 CO
2
H 或 COSH 所组成的基团与 SO
3
H 所组成的基团数目至少相同的稳定染料,以及水性载体。稳定染料可以提高油墨组合物的可靠性和性能。添加稳定染料可以减少或防止因墨水中存在粘合剂而形成堵塞喷头通孔和喉管的材料。墨水组合物可以减少在喷头寿命期间保留喷头所有喷嘴所需的维护量。
