Alkynylboronates can be employed as a practical and versatile precursor for a variety of p-conjugated organic compounds. In the presence of Cu(I) salt, cross-coupling reactions of acid chlorides with alkynylboronates giving rise to the corresponding conjugated ynones takes place readily in aprotic p

Cross-coupling reactions of bis(ferrocenyl)mercury with aryl-and heteroaryl iodides were shown to be easy and convenient for the synthesis of monoarylsubstituted ferrocenes in high yields. The highly selective substitution of iodine atom in iodobromoarenes by the ferrocenyl unit was demonstrated.
