prepartion of Pd(dba)2?
« on: May 20, 2009, 02:08:11 AM »
I would like to synthesis of the Pd(dba)2. Usually, we would be able to buy Pd2(dba)3 not Pd(dba)2.
Is there any reference of synthetic method?
Thanks.

hi,

the original publication : JOMC, 65,253, 1974

Pd(dba)2 is the crude compound obtained from the reaction, which is an equimolecular mixture of Pd(dba)3 and Pd2(dba)3. Pd2(dba)3.solvent is obtained after crystalisation of the mixture, which displace a dba and form just the previous complex.
