Abstract:
We report herein a palladium-catalyzed three-component cross-coupling reaction of 2-(trimethylsilyl)phenyl trifluoromethanesulfonate, benzylic/allylic bromides and 1,1-bis[(pinacolato)boryl]methane. The reaction, which affords benzyl boronates as the products, represents the first example of using 1,1-bis[(pinacolato)boryl]methane in a cross-coupling reaction involving benzyne species.

Abstract:
It is over 100 years since scientists first postulated the existence of arynes as reactive intermediates. Their use in organic synthesis is now well-established and investigations into novel methods for their generation and utility in carbon-carbon bond forming reactions continue to this day. In 1983 Kobayashi and co-workers introduced a novel method of generating benzyne under mild conditions, using a fluoride induced decomposition of 2-(trimethylsilyl)phenyl triflate 1. This development has opened the door to employing arynes in a variety of transitionmetal mediated carbon-carbon bond formin

Abstract:
This thesis is divided into two main chapters, which are focused on two separated and uncorrelated research areas. The first part of this thesis is dedicated to the research I carried out in benzyne chemistry and the second part is focused on catalytic C-H bond activation. In the first place, a novel insertion reaction of arynes into the nitrogen-carbonyl σ-bond of amides has been investigated as a rapid and powerful approach for the preparation of valuable ortho-disubstituted arenes. Readily available aromatic amides undergo smooth insertion when treated with O-triflatophenyl silane aryne pre

The first chapter describes nickel-catalyzed cyclization of aryne precursors with allene and diyne derivatives resulting in the formation of 9,10-dihydrophenanthrene and naphthalene derivatives in moderate to excellent yields. The second chapter extends the aryne precursors to precede 1,3-dipolar cycloaddition and coupling reaction with azide and isocyanate derivatives to form benzotri

Abstract:
Tosylates are among the least expensive, but also among the least reactive toward Pd(0) oxidative addition, of aryl sulfonates. Jie Wu of Fudan University has now devised conditions (J. Org. Chem. 2007, 72, 9346) for the Pd-catalyzed coupling of aryl tosylates such as 1 with arene trifluoroborates. Kei Manabe of RIKEN has found (Organic Lett. 2007, 9, 5593) that an ortho OH activates an adjacent Cl for Pd-mediated coupling, allowing the conversion of 4 to 6 .

Abstract:
Diaryl ethers are one of the most essential intermediates for organic synthesis in the fields of medicine, agrochemistry, and polymer sciences. There are many naturally occurring biologically active compounds bearing a diaryl ether group including the antibiotic vancomycin, perrottetines, and chloropeptins (anti-HIV agents). This chapter presents efficient and practical synthetic methods for the synthesis of diaryl ethers including Ullmann-type reactions of aryl halides which are achieved using copper catalysts, Buchwald–Hartwig cross-couplings of aryl halides in the presence of palladium cata
