Bulky Diamine Ligand Promotes Cross-Coupling of Difluoroalkyl Bromides by Iron Catalysis

Although iron-catalyzed cross-coupling of Grignard reagents with alkyl halides has been well established, the adoption of the reaction for fluoroalkylations has not been reported because traditional catalytic systems often lead to defluorination reactions. Described herein is the investigation of an iron-catalyzed cross-coupling between arylmagnesium bromides and difluoroalkyl bromides with modified N,N,N′,N′-tetramethyl-ethane-1,2-diamine (TMEDA) as a ligand. The use of this bulky diamine, in which a butylene is substituted at one carbon atom of the ethylene backbone in TMEDA, enables the iron-catalyzed difluoroalkylation under mild reaction conditions with a wide range of difluoroalkyl bromides, including vulnerable bromodifluoromethane, thus providing a general and cost-efficient route for applications in medicinal chemistry.

Low-Temperature Reductive Aminolysis of Carbohydrates to Diamines and Aminoalcohols by Heterogeneous Catalysis

Short amines, such as ethanolamines and ethylenediamines, are important compounds in today's bulk and fine chemicals industry. Unfortunately, current industrial manufacture of these chemicals relies on fossil resources and requires rigorous safety measures when handling explosive or toxic intermediates. Inspired by the elegant working mechanism of aldolase enzymes, a novel heterogeneously catalyzed process—reductive aminolysis—was developed for the efficient production of short amines from carbohydrates at low temperature. High-value bio-based amines containing a bio-derived C2 carbon backbone were synthesized in one step with yields up to 87 C%, in the absence of a solvent and at a temperature below 405 K. A wide variety of available primary and secondary alkyl- and alkanolamines can be reacted with the carbohydrate to form the corresponding C2-diamine. The presented reductive aminolysis is therefore a promising strategy for sustainable synthesis of short, acyclic, bio-based amines.

Amine catalyst for producing polyurethane and polyisocyanurate

An amine catalyst-for production of a polyurethane and a polyisocyanurate is provided which comprises a quaternary ammonium compound represented by General Formula (1): where R1 to R6 are independently a linear or branched saturated hydrocarbon group of 1 to 4 carbon atoms; R7 and R8 are independently a linear or branched, saturated or unsaturated hydrocarbon group of 2 to 12 carbon atoms; n is a number of 0 to 3 provided that at n=o any one of R1, R2 and R3, and R5 and/or R6 may be linked together to form a heterocycle, or at n=1, 2, or 3, R5 or R6 and R4 may be linked together to form a heterocycle; A is a carbonate group or an organic acid group; and X is number of 1 to 2. The catalyst has high activity in formation of polyurethane foams and polyisocyanurate foams, having less odor, and producing foams of high fire retardance, having high curability, high retarding effect, and low corrosiveness.
