Carbamoyl chlorides derived from secondary aliphatic amines having alkyl groups which are branched in the 1-position are prepared by passing phosgene at an elevated temperature into the corresponding, initially taken--if appropriate dissolved in an inert solvent--secondary aliphatic amines having alkyl groups which are branched in the 1-position. The reaction products are intermediates in various specialized fields, particularly in the plant protection sector.

preparing N,N-disubstituted carbamoyl chlorides by using chlorocarbonylsulfenyl chloride as a carbonylating agent. It comprises the reaction of secondary amines with chlorocarbo- nylsulfenyl chloride in the presence of an aprotic organic solvent to produce the corresponding N,N-disubstituted carba- moyl halides. Insertion of the carbonyl group without using phosgene is the novelty of this method. Resume

A method of enhancing binding of cells to an integrin-binding ligand comprises treating integrin-expressing cells in vitro with an agonist of integrin, wherein the integrin is selected from the group consisting of α4β1, α5β1, α4β7, αvβ3 and αLβ2, and contacting the treated cells with an integrin-binding ligand; integrin agonist compounds having the general formula I; methods of treating integrin-expressing cells with such agonists to enhance binding; and therapeutic methods comprising administering agonist-treated cells or agonist compounds to a mammal.
