Reactions of anthrone with nontransition and transition metal alkoxides.

Hydrophosphination reactions with transition metal ferrocenylphosphine complexes.

The group 6 metal mono-, bis- and tris-ferrocenylphosphine complexes [M(CO)5(PH2Fc)] (1a, M = Cr; 1b, M = Mo; 1c, M = W), cis-[M(CO)4(PH2Fc)2] (2a, M = Cr; 2b, M = Mo; 2c, M = W) and fac-[M(CO)3(PH2Fc)3] (3a, M = Cr; 3b, M = Mo; 3c, M = W) [Fc = Fe(η(5)-C5H4)(η(5)-C5H5)] were prepared and fully characterised. IR and NMR spectroscopy and single-crystal X-ray diffraction analysis indicate that Fc...

Reactions of Amino-imino-boranes with Transition Metal Halides and Substituted Transition Metal Halides

The aminoiminoborane tmp-B=NCMe3 (1) adds to TiBr4 or ZrCL in a 1:1 ratio while PdCh adds 1 in a 1:2 ratio. In these new compounds the NBN unit is almost linear and the configuration corresponds to an allene. On the other hand 1 and Ti(OR)4 compounds and Ti(NMe2)4 give N metallated diaminoboranes tmp-B(X)-NCMe3EX3 (X = OR, NMe2). Mixed compounds Ti(OR)3_„X„ lead to diaminoboranes with BOR group...

Investigations into Transition-Metal-Catalyzed Arene Trifluoromethylation Reactions Transition-Metal-Catalyzed Arene Trifluoromethylation Reactions

Trifluoromethyl-substituted arenes and heteroarenes are widely prevalent in pharmaceuticals and agrochemicals. As a result, the development of practical methods for the formation of aryl–CF3 bonds has become an active field of research. Over the past five years, transition-metal-catalyzed cross-coupling between aryl–X (X = halide, organometallic, or H) and various ‘CF3’ reagents has emerged as ...

Potassium Alkoxides and Thiolates in Transition Metal- Free Synthesis: Mechanism and Application

Transition metal-catalyzed allylic substitution reactions with unactivated allylic substrates.

The transition metal-catalyzed allylic substitution of unactivated allylic substrates (allylic alcohols, allylic ethers and allylic amines) is rapidly becoming an important area of research. There are several advantages to using these substrates in allylic substitution reactions: the use of unactivated alcohols minimizes the production of waste by-products and reaction steps; and allylic ethers...
