The m- and p-APha isomers are commercially available. The synthesis of Boc-o-APha-OH and its ethyl and tert-butyl esters by carboxylation of the dianion of Boc-o-methylaniline has been briefly mentioned. 63 Whereas the carboxy group in APha is expected to react normally, the aromatic amino function is expected to be less nucleophilic owing to the delocalization of the nitrogen lone pair. However, deactivation should be less significant than in o- and p-Abz. Only a few hints at this conclusion may be found in the literature. Indeed, coupling of Boc-p-APha-OSu to an aliphatic primary amine was conducted in DMF for 2 h, affording the amide in a 75% yield. 64 ... 

Nevertheless, even under conditions for which diffusion limitations could be excluded, MCHA was still converted directly to MCH. By adding substantial partial pressures of H2S, it was shown that the formation of MCH resulted from the nucleophilic substitution of MCHA to give 2-methylcyclo-hexylthiol and subsequent fast hydrogenolysis to give MCH. These results mean that the network of the HDN of anilines is quite complex the network of o-methylaniline (o-toluidine) is shown in Scheme 19.

Abstract MoP/Si02 and M0P/AI2O3 can be prepared by treating supported Mo metal particles with phosphine and hydrogen. The resulting materials have high activities in the hydrodesulfurization of dibenzothiophene and the hydrodenitrogenation of o-methylaniline. 

Fig. 3 HDN conversions of o-methylaniline in the absence of H2S, in the presence of 3 kPa H2S and after removal of H2S (a) and product selectivities (b) in the absence of H2S (closed symbols) and in the presence of 3 kPa H S (open symbols) over 13 wt% MoP/Si02.

Our results demonstrate that MoP particles on a support can be prepared successfully by treating Mo metal particles with phosphine and hydrogen. In contrast to the preparation of supported Ni2P, it is necessary to heat at higher temperatures (773 or 873 K) in H2 after reaction with PH3 at 523 K to prepare the supported MoP catalyst. The resulting MoP/Si02 and M0P/AI2O3 catalysts proved to be veiy active in the HDS of dibenzothiophene and the HDN of o-methylaniline, both in the presence and absence of H2S.
