Frequently asked questions

Q1. What have the authors contributed in "Hetero-multimetallic tetrakis(scs-pincer palladium)-(metallo)porphyrin hybrids. tunable precatalysts in a heck reaction" ?

Manganese and nickel were introduced into the porphyrin macrocycle prior to peripheral electrophilic palladation, whereas magnesium was introduced thereafter in light of its acid sensitivity.
