[reaction: see text] Negishi-type cross-coupling reaction was effected by employing organozincs and anhydrides or mixedanhydrides that formed in situ fromsodiumsalts of the corresponding acids and ethyl chloroformate under the catalysis of palladium(0). A general method for preparing symmetrical/unsymmetrical ketones was developed.
Micro-nano materials, products obtained by covalently modifying the surfaces of micro/nano materials with hydrophilic materials, and methods for making the same. The micro/nano materials on the surfaces have carboxyl groups or/and pro-carboxyl groups which are converted into their active esters. The products are covalently modified by forming amide bonds between the active esters on the surfaces and the modification agents; where the modification agents are hydrophilic compounds and/or hydrophilic polymers bearing primary and/or secondary aliphatic amines. Monomers bearing carboxyl groups and/or pro-carboxyl groups are used to produce an adequate number of carboxyl groups and/or pro-carboxyl groups on the surface of a polymer material to be modified. The carboxyl groups and/or pro-carboxyl groups are converted into active esters. A reasonably-sized modification agent bearing primary and/or secondary amines, zwitterions and hydrophilic linear spacer arms is used to form amide bonds and obtain a covalently modified surface layer.

complexes with different modes of the carboxylate binding, from chelating, through bridging (syn-syn, syn-anti, monatomic), ionic to monodentate were used for the study, namely [Zn(C6H5CHCHCOO)2(H2O)2] (I) with chelating carboxylate group (C6H5CHCHCOO=cinnamate), [Zn2(C6H5COO)4(pap)2] (II) with syn-syn bridging carboxylate (C6H5COO=benzoate; pap=papaverine), [Zn(C6H5CHCHCOO)2(mpcm)]n (III) with syn-anti
