Single-catalyst System

Furthermore, a one-pot indole synthesis starting from o-chloroiodoben-zenze was also achieved using a single catalyst system consisting of Pd(OAc)2, Cul, IPr HC1 and CS2CO3. 

Gallosilicate Catalysts. Aromatization of Propane and Butane. Cyclar Process. The Cyclar process, which was discovered by BP and jointly developed with UOP, uses a single catalyst system to convert propane and butanes into aromatic hydrocarbons at high selectivity. The catalyst consists of a zeolite with a non-noble metal promoter. The zeolite component provides a shape-selective acid function, and the non-noble metal additive acts as a dehydrogenation catalyst. ... 

Alkane Metathesis by Single-Catalyst Systems 43 Alkane metathesis activity of different catalysts... 

In this section, the tandem system comprising of two catalysts for the alkane metathesis reaction will be discussed one catalyst for the dehydrogena-tion/hydrogenation steps and another one for the olefin metathesis step. In contrast to the multifunctional, single-catalyst systems, there are only a few reports that describe tandem, dual-catalyst systems for the alkane metathesis reaction [100]. Herein, the Chevron system will be discussed [8], followed by the recent development of another dual-catalytic system developed by Goldman and Brookhart [18].

While CCTP character has been demonstrated in several single catalyst systems, examples of the use of main-group metals to exchange polymer chains between two different catalysts in a common reaction environment are much less common. Dual-catalyst systems claimed to demonstrate some level of reversible chain transfer (see Table 7) are summarized below for both ethylene- and propylene-based systems. Characterization data demonstrating that the primary product is BCP are described in greater detail in Section 3.22.9.
