The vapor deposition of many Mo-containing films relies on the delivery of volatile compounds with the general bis(tert-butylimido)molybdenum(VI) framework, both in at. layer deposition and CVD. The authors prepared (tBuN)2MoCl2 adducts using neutral N,N’-chelates and studied their volatility, thermal stability, and decomposition pathways. Volatility was determined by TGA, with the 1,4-di-tert-butyl-1,3-diazabutadiene adduct (5) found to be the most volatile (1 torr of vapor pressure at 135°). Thermal stability was measured primarily using DSC, and the 1,10-phenanthroline adduct (4) is the most stable with an onset of decomposition of 303°. The authors have also studied Mo compounds with other alkyl-substituted imido groups: these compounds all follow a similar decomposition pathway, γ-H activation, with varying reaction barriers. The tert-pentyl, 1-adamantyl, and a cyclic imido (from 2,5-dimethylhexane-2,5-diamine) were systematically studied to probe the kinetics of this pathway. All of these compounds were fully characterized, including via single-crystal x-ray diffraction, and a total of 19 new structures are reported.2,5-Dimethyl-2,5-hexanediol (cas: 110-03-2) were involved in the experimental procedure.
2,5-Dimethyl-2,5-hexanediol(cas:110-03-2) is used as an intermediate in the preparation of 2.5-Dimethyl-2.5-bis(tertbutyl-peroxy)hexane. It is also used in the synthesis of six- and seven-membered heterocyclic boron compounds.Electric Literature of C8H18O2
