You, Jingsong et al. published their research in Angewandte Chemie, International Edition in 2003 | CAS: 5351-07-5

2-(4-Methoxyphenyl)-2-methylpropanenitrile (cas: 5351-07-5) belongs to nitriles. Nitrile carbon shifts are in the range of 115–125 ppm whereas in isonitriles the shifts are around 155–165 ppm. In conventional organic reductions, nitrile is reduced by treatment with lithium aluminium hydride to the amine. Reduction to the imine followed by hydrolysis to the aldehyde takes place in the Stephen aldehyde synthesis, which uses stannous chloride in acid.SDS of cas: 5351-07-5

A general method for the direct α-arylation of nitriles with aryl chlorides was written by You, Jingsong;Verkade, John G.. And the article was included in Angewandte Chemie, International Edition in 2003.SDS of cas: 5351-07-5 This article mentions the following:

The long-standing challenge of developing a general method for the title methodol. is met for a broad range of aryl chlorides through the use of bicyclic P(iBuNCH2CH2)3N as bulky electron-rich ligand for palladium. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenyl)-2-methylpropanenitrile (cas: 5351-07-5SDS of cas: 5351-07-5).
