The authors are sorry to report that the yield of the hydrosilylation reaction in [P44414][NTf2] (1) IL with [RhCl(PPh3)3] was replaced with the yield reported for [P44414][NTf2] (1) IL with K2PtCl4 in their published paper [1]. Due to this fact, we would like to replace Table 1 and Figure 3, and make four changes in manuscript text to correct this mistake. Due to mislabeling, the following table and figure must be replaced:

Moreover, there are four mistakes in the article text:
  • On page 3, lines 32–34, the sentence “[P44414][NTf2] (1) IL system shows satisfying yields close to 100% throughout the whole five reaction cycles for catalysts such as K2PtCl4, Pt(PPh2)2Cl2 and Karstedt catalyst (100% yield up to fourth cycle)” should be replaced with “[P44414][NTf2] (1) IL system shows satisfying yields close to 100% throughout the whole five reaction cycles for catalysts such as [RhCl(PPh3)3], Pt(PPh3)2Cl2 and Karstedt catalyst (100% yield up to fourth cycle)”.
  • On page 3, lines 38 and 39, the sentence “The least effective catalyst for IL (1) is rhodium catalyst for which a major drop in yield was observed after the first reaction cycle” should be replaced with “The least effective catalyst for IL (1) is platinum catalyst, K2PtCl4, for which a major drop in yield was observed after the first reaction cycle”.
  • On page 7, lines 10–12, the sentence “[the] most efficient IL systems for hydrosilylation reaction were [P44414][[NTf2] (1)/K2PtCl4 and [P44414][NTf2] (1)/Pt(PPh2)2 for which yields after a fifth cycle were maintained at a level of more than 80%.” should be replaced with “The most efficient IL systems for hydrosilylation reaction were [P44414][[NTf2] (1)/[RhCl(PPh3)3] and [P44414][NTf2] (1)/Pt(PPh3)4, for which yields after a fifth cycle were maintained at a level of more than 80%”.
  • On page 7, lines 15 and 16, the statement “which in four out of seven tested IL systems shows [an] immediate drop of the catalyst activity when being recycled for the first time.” should be replaced with “which in three out of seven tested IL systems shows an immediate drop of the catalyst activity when being recycled for the first time”.
The authors would like to apologize for any inconvenience caused to the readers by these changes.
