[Restoration of function by microsurgical reconstruction after sarcoma excision in the upper limb]. / Funktionserhalt durch mikrochirurgische Rekonstruktion nach Sarkomresektion an der oberen Extremität.

The treatment of soft tissue sarcomas includes different modalities, but the complete excision of the tumor is the most important one. It is often difficult to resect the tumor completely and simultaneously restore a good function of the upper limb. Therefore a microsurgical reconstruction is often necessary as demonstrated here.

A "hard/soft" mismatch enables catalytic Friedel-Crafts acylations.

[figure: see text] Cationic complexes of Pt(II) and other late transition metals efficiently catalyze Friedel-Crafts acylations of moderately activated arenes by carboxylic acid anhydrides. The nature of the catalytically relevant species formed from (PhCN)2PtCl2 and AgSbF6 and their interactions with the substrates are studied by NMR and ESI-MS.
