Title: Selenenate Anions (PhSeO − ) as Organocatalyst: Synthesis of trans ‐Stilbenes and a PPV Derivative
Abstract

The selenenate anion (RSeO) is introduced as an active organocatalyst for the dehydrohalogen coupling of benzyl halides to formtrans‐stilbenes. It is shown that RSeOis a more reactive catalyst than the previously reported sulfur analogues (sulfenate anion, RSO) and selenolate anions (RSe) in the aforementioned reaction. This catalytic system was also applied to the benzylic‐chloromethyl‐coupling polymerization (BCCP) of a bis‐chloromethyl arene to form ppv (poly(p‐phenylene vinylene))‐type polymers with high yields, Mn(average molecular weight) up to 13,000 and Đ (dispersity) of 1.15.

  1. Abstract

    Diverse alkenylboronic acids react smoothly with varioussp3‐carbon electrophiles such as unactivated alkyl triflates in the presence of mild bases such as K3PO4. The reaction protocol is very mild and thereby enables high functional group tolerance. This transition metal‐free condition is orthogonal towards the classic transition metal catalyzed Suzuki coupling.

  2. Abstract

    Direct preparation of alkylated amide‐derivatives by cross‐coupling chemistry using sustainable protocols is challenging due to sensitivity of the amide functional group to reaction conditions. Herein, we report the synthesis of alkyl‐substituted amides by iron‐catalyzed C(sp2)−C(sp3) cross‐coupling of Grignard reagents with aryl chlorides. The products of these reactions are broadly used in the synthesis of pharmaceuticals, agrochemicals and other biologically‐active molecules. Furthermore, amides are used as versatile intermediates that can participate in the synthesis of valuable ketones and amines, providing access to motifs of broad synthetic interest. The reaction is characterized by its good substrate scope, tolerating a range of amide substitution, including sterically‐bulky, sensitive and readily modifiable amides. The reaction is compatible with challenging organometallics possessing β‐hydrogens, and proceeds under very mild, operationally‐simple conditions. Optimization of the catalyst system demonstrated the beneficial effect of O‐coordinating ligands on the cross‐coupling. The reaction was found to be fully chemoselective for the mono‐substitution at the less sterically‐hindered position. Mechanistic studies establish the order of reactivity and provide insight into the role of amide to control mono‐selectivity of the alkylation. The protocol provides the possibility for convenient access to alkyl‐amide structural building blocks using sustainable cross‐coupling conditions with high efficiency.

  3. Abstract

    Aryl tosylates are an attractive class of electrophiles for cross‐coupling reactions due to ease of synthesis, low price, and the employment of C−O electrophiles, however, the reactivity of aryl tosylates is low. Herein, we report the Ni‐catalyzed C(sp2)−C(sp3) Kumada cross‐coupling of aryl tosylates with primary and secondary alkyl Grignard reagents. The method delivers valuable alkyl arenes by cross‐coupling with challenging alkyl organometallics possessing β‐hydrogens that are prone to β‐hydride elimination and homo‐coupling. The reaction is catalyzed by an air‐ and moisture stable‐Ni(II) precatalyst. A broad range of electronically‐varied aryl tosylates, including bis‐tosylates, underwent this transformation, and many examples are suitable at mild room temperature conditions. The combination of Ar−X cross‐coupling with the facile Ar−OH activation/cross‐coupling strategy permits for orthogonal cross‐coupling with challenging alkyl organometallics. Furthermore, we demonstrate that the method operates with TON reaching 2000, which is one of the highest turnovers observed to date in Ni‐catalyzed cross‐couplings.

  4. Abstract

    Benzofused lactams, especially indolin‐2‐one and dihydroquinolin‐2‐one are popular structural motives in durgs and natural products. Herein, we developed a room temperature and robust synthesis of benzofused lactams through cobalt(III)‐catalyzed C(sp2)−H amidation. In this protocol, in‐situ formation of Cp*Co(III)(ligand) catalyst from Cp*Co(CO)I2and ligand simplify the synthetic effort of cobalt complexes. Simple and readily synthesized 1,4,2‐dioxazol‐5‐ones underwent room temperature intramolecular C−H amidation and afforded a wide variety of functionalized benzofused lactams in up to 86% yield. The scalability of the reaction is also be demonstrated.
