Usage

Uses

Used in Organic Synthesis:
Triisobutylborane is used as a reducing agent for the conversion of aldehydes and ketones to alcohols, a process that is crucial in the synthesis of a wide range of organic compounds. Its ability to facilitate this transformation makes it an essential tool in the field of organic chemistry.
Used in Hydroboration Reactions:
In the chemical industry, triisobutylborane is employed as a catalyst in hydroboration reactions, which involve the addition of borane (BH3) across the double bond of alkenes. This reaction is a key step in the synthesis of various organic compounds, highlighting the versatility of triisobutylborane in chemical processes.
Used in Controlled Environments:
Due to its reactivity and flammability, triisobutylborane is used with caution in controlled environments. Special handling and storage protocols are necessary to ensure safety during its use in chemical reactions and processes.

Ternary metallocene catalyst systems based on metallocene dichlorides and AlBu3i/[PhNMe2H] [B(C6F5)4] NMR investigations of the influence of Al/Zr ratios on alkylation and on formation of the precursor of the active metallocene species

The formation of the precursors of the polymerization-active species of the metallocene dichlorides Cp2ZrCl2 and Ph2C(CpFlu)ZrCl2 by successive reaction with AlBu3i and [PhNMe2H][B(C6F5)4] was investigated by means of NMR spectroscopy. More than two equivalents of AlBu3i are required for total conversion of the metallocene dichlorides in the first step. The reaction of Ph2C(CpFlu)ZrCl2 with AlBu3i leads exclusively to the mono-iso-butyl complex Ph2C(CpFlu)ZrClBui, independent of the surplus AlBu3i used, whereas in the case of Cp2ZrCl2 a series of metallocene products are observed, depending on the Al/Zr ratio used. When this ratio was increased to above 10, the reaction could be exclusively directed to form the dimer metallocene complex [Cp2ZrH2· AlBu3i]2. The reaction of [PhNMe2H][B(C6F5)4] with metallocene/aluminium alkyl mixtures prepared with 10, 20, 50 and 100 equivalents of AlBu3i leads to the precipitation of an oily liquid, which contains resulting cationic metallocene complexes. These liquid phases can be purified by extraction and subsequently used for NMR measurements. With one exception, mixtures of two or three different cationic metallocene products are obtained, depending on the Al/Zr ratio and on the metallocene ligand used. An Al/Zr ratio of 100 the reaction of the Ph2C(CpFlu)ZrCl2/AlBu3i mixture with [PhNMe2H][B(C6F5)4] exclusively leads to the cationic heterodinuclear metallocene complex [Ph2C(CpFlu)Zr-μ-H-μ-(C4H7)- AlBu3i]+, a novel type of allyl-bridged cation, which was characterized by NMR data. None of the reactions of metallocene dichloride/aluminium alkyl mixtures with [PhNMe2H][B(C6F5)4] lead to the degradation of [B(C6F5)4]-, whereas in the absence of metallocenes AlBu3i reacts with [PhNMe2H][B(C6F5)4] to give AlBu3-xi(C6F5)x compounds. Based on these results and with additional information from the literature a mechanism is proposed to explain the formation of [Ph2C(CpFlu)Zr-μ-H-μ-(C4H7) -AlBu2i]+. 2002 Published by Elsevier Science B.V.

Reaction of AlR3 with [CPh3][B(C6F 5)4]: Facile degradation of [B(C6F 5)4]- by transient [AlR2] +

Trimethylaluminum reacts with [CPh3][B(C6F 5)4] at elevated temperatures to give a mixture of AlMe3-x(C6F5)x compounds, depending on the Al/B ratio. AlBui3 reacts significantly faster under β-hydride abstraction. The Al-C6F5 species rapidly react with Cp2ZrMe2 or [Cp2ZrMe] + under C6F5 transfer to give poorly active Cp2ZrMe(C6F5); this reaction may have implications for the deactivation of Cp2ZrMe2/AlR 3/[CPh3][B(C6F5)4] olefin polymerization catalysts.
