The conversion of a eta (2)-bonded propene (complex 1) into a bridging eta (1),eta (3)-allyl moiety (complex 4) is reported. The formation of 4 occurs through the following sequence of reactions: deprotonation of the methyl group of the coordinated propene in 1 and formation of the eta (1)-allyl complex 2, displacement of the eta (2)-olefin of a second molecule of 1 by the eta (1)-allyl moiety of 2 and formation of the eta (1),eta (2)-allyl-bridged dinuclear complex 3, and finally further deprotonation of the eta (1)-bonded methylene group of 3 and simultaneous release of a chloride ion by one platinum unit leading to formation of the eta (1),eta (3)-allyl-bridged platinum dimer 4.

Bis deprotonation of a platinum(II)-bonded propene affords an unprecedented eta1, eta3-allyl moiety bridging two metal centers

Abstract

The conversion of a eta (2)-bonded propene (complex 1) into a bridging eta (1),eta (3)-allyl moiety (complex 4) is reported. The formation of 4 occurs through the following sequence of reactions: deprotonation of the methyl group of the coordinated propene in 1 and formation of the eta (1)-allyl complex 2, displacement of the eta (2)-olefin of a second molecule of 1 by the eta (1)-allyl moiety of 2 and formation of the eta (1),eta (2)-allyl-bridged dinuclear complex 3, and finally further deprotonation of the eta (1)-bonded methylene group of 3 and simultaneous release of a chloride ion by one platinum unit leading to formation of the eta (1),eta (3)-allyl-bridged platinum dimer 4.
