Bis(arylimido) Molybdenum(VI) Amidinate and Guanidinate Complexes; Molecular Structures of [(ArN)2MoMe{N(Cy)C[N(i-Pr)2]N(Cy)}] (Ar = 2,6-i-Pr2C6H3; Cy = Cyclohexyl) and [(2,6-i-Pr2C6H3N)2MoCl2] · [NH=C(C6H5)CH(SiMe3)2]
Abstract:The reaction of [(ArN) 2 MoCl 2 ]´DME (Ar = 2,6-iPr 2 C 6 H 3 ) (1) with lithium amidinates or guanidinates resulted in molybdenum(VI) complexes [(ArN) 2 -MoCl{N(R 1 )C(R 2 )N(R 1 )}] (R 1 = Cy (cyclohexyl), R 2 = Me (2); R 1 = Cy, R 2 = N(i-Pr) 2 (3); R 1 = Cy, R 2 = N(SiMe 3 ) 2 (4); R 1 = SiMe 3 , R 2 = C 6 H 5 (5)) with five coordinated molybdenum atoms. Methylation of these compounds was exemplified by the reactions of 2 and 3 with MeLi affording the corresponding methylates [(ArN) 2 MoMe{N(R 1 )C(R 2 )N(… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
