and aryl amides and challenging esters, with a low-cost and bench-stable boron source, providing boronates with exclusive selectivity, high efficiency, and high turnover number (up to 8900). This novel strategy may offer a versatile and environmentally friendly alternative to current methods for selective C(sp3 )-H borylation that employ even more expensive metals, such as iridium and rhodium.
nickel-catalyzed alkoxycarbonylation of aromatic iodides with alcoholsunder atmospheric pressure of carbonmonoxide is presented here. This operationally simple protocol allows the facile synthesis of (hetero)aromatic esters, exhibiting broad substrate scope with excellent functional group tolerance. Various primary and secondary aliphatic alcohols as well as phenols are suitable for this transformation

A nonaqueous ink composition for an ink jet recording, comprising
(A) a urethane resin dispersant with an acidic functional group,
(B) a pigment, and
(C) an organic solvent [and optionally (D) a thermal reactive compound],
characterized in that
the urethane resin dispersant (A) is a branched urethane resin dispersant prepared by polymerizing a terminal-isocyanate-containing compound (p), which has been prepared by reacting
(a) a polyisocyanate having three or more isocyanate groups, and
(b) a monoalcohol,
under the condition that a molar ratio (Ma/Mb) of the number of moles (Ma) of isocyanate groups (NCO) from the polyisocyanate (a) to the number of moles (Mb) of hydroxyl groups (OH) from the monoalcohol (b) is 3/2 to 3/0.5,
(c) a compound having one or more acidic groups and two or more hydroxyl groups, and
(q) a polyol compound having two or more hydroxyl groups via 1 to 30 atoms,
under the condition that the hydroxyl groups are in excess; and
in that 25% to 60% by weight of the polyisocyanate (a) is used with respect to a total amount of nonvolatile components in the branched urethane resin dispersant, is disclosed.
