Thermal decomposition studies on platinacycloalkanes of the type Pt(CH 2)mL2 (where m = 6,7,8,10 and L2 = dppp {1,3-bis(diphenylphosphino)propane}, dppe {1,2-bis(diphenylphosphino) ethane} or L = PPh3, tBu3P) are described. The results reveal that the organic product distribution depends on various factors such as the nature of ligand, the metal system, the mode of decomposition, the ring size and the temperature. Possible mechanistic pathways for the formation of various products are discussed. These platinacycloalkanes can be used as models for metallacycloalkane intermediates in catalytic reactions.

Coming full circle: Bis(alkenyl)-platinum(II) complexes cis-[L 2Pt-{(CH2)nCH=CH2}2] (L = PPh3 or L2 = Ph2P(CH2) 3PPh2; n = 3-6) have been prepared and fully characterized. Ring-closing metathesis leads to new platinacycloalkenes, which can be hydrogenated to platinacycloalkanes with 9-, 11-, 13-, and 15-membered rings (see picture for 15-membered ring; Pt green, P orange, C blue, H white).

Reaction of the bis-alkenyl complex cis-[Pt(PPh3) 2-(CH2CH2CH=CH2)2] with Grubbs 1st generation catalyst gives, in high yield, the metallacycloalkene cis-[Pt(PPh3)2(CH
