  The air and water stable non-symmetrical pincer palladacycle [Me2NCH2(Cl)C=C(CH2)2OP(i-Pr)2-kNkCkP]PdCl 5, easily prepared from the chloropalladation of the hetero-substituted alkyne Me2NCH2C≡C(CH2)2OP(i-Pr)2, is a highly efficient catalyst precursor for the coupling of aryl boronic acids and aryl chlorides. Both electron-rich and electron-poor aryl chlorides are efficiently coupled in the presence of 5 to furnish the corresponding cross-coupled products in excellent yields, and a wide variety of functional groups are tolerated in both aryl chloride and aryl boronic acid.

  由杂取代炔 Me2N C≡C(CH2)2OP(i-Pr)2 的氯钯化反应简易制备而成的空气和水稳定的非对称钳形链锁[Me2N (Cl)C=C( )2OP(i-Pr)2-kNkCkP]PdCl 5 是芳基硼酸和芳基氯化物偶联反应的高效催化剂前体。在 5 的存在下，富电子和贫电子的芳基氯化物都能高效地偶联，以优异的产率得到相应的交叉偶联产物，而且芳基氯化物和芳基硼酸中都能容许多种官能团。

  An efficient synthetic procedure was developed for preparation of oxygen-containing propargylamines with high yields and selectivity by aminomethylation of propargyl alcohols and their esters with gem-diamines catalyzed by complexes and salts of d-transition metals and lanthanides.
• The retro-chloropalladation reaction of heterosubstituted alkynes

  The bridge-splitting reaction of dimeric palladacycles of the type Pd[kappa(1)-C, kappa(1)-N-C(R) = C(Cl)CH2NMe2](mu-Cl)}(2) (R = Ph, Me, CH2CH2OH), derived from the chloropalladation of propargyl amines (RCdropCCH(2)NMe(2)), with pyridine (Py), triphenylphosphine (PPh3) and tert-butytisonitrile ((BuNC)-Bu-t) affords the monomeric compounds [PdC(R)=CCH2NMe2(Cl)L] (L = Py, PPh3, (BuNC)-Bu-t). These monomeric compounds are not stable in solution and undergo retro-chloropalladation reactions yielding the propargyl amines and [PdCl(L)-mu-Cl](2). This process is strongly dependent upon the nature of the incoming nucleophile (L), the R group on the metallated ligand and the temperature. The retro-halopalladation reaction is almost instantaneous in the case of the reaction of the bromo derivative [PdC(Ph)=C(Br)CH2NMe2-mu-Br](2) and pyridine at room temperature. These results can be rationalized in terms of the stability of the Pd-C bond of the intermediate monomeric compound [PdC(R)=C(X)CH2NMe2(X)L], that is directly related to the nature of its substituents R (Ph, Me and CH2CH2OH), of ligands which are both cis and trans to it (Py, (CNBu)-Bu-t, PPh3, Cl and Br) and the temperature.
