Thiacalixarenes bearing phenylazo or ethynylic groups on the lower rims were prepared and fully characterized. The functional groups were chosen for their ability to increase the electron delocalisation over the molecule and to form metal complexes. The f

The reaction between alkynylstannanes (3,4) and trans- (1) gives trans-CR> (5) or trans-CR1)2 (6) in high yield (R1=H, Me, Ph).Complexes 5 react with alkynylstannanes to give the unsymmetrical bis(alkynyl) complexes 7, trans-CR2)CCR1> (R1=Me, Ph; R2=H).Although the palladium(II) dichloride 2, trans-, reacts much faster with alkynylstannanes than 1, the compounds trans-CR1)2> (9) are always obtained as mixtures with trans-CR1> (8), except for R1=H.Compounds 8 can be obtained pure for R1=Me or t-Bu if the reaction between 2 and 3 is carefully controlled.The dependence of the product distribution under experimental conditions in the case of the palladium(II) acetylides indicates that oxidative addition-reductive elimination reactions are involved.The crystal structure of trans-CMe)2> (6b) has been determined.All the products have been characterized by 13C, 31P and 195Pt NMR spectroscopy.
