The traffic to be carried by today's European backbone networks increases very rapidly. An important portion of this traffic consists of data traffic (mainly IP-related). In the future data traffic is expected to become the abundantly dominant traffi

Publikováno v: Organometallics. 20:4040-4048

The carbene-C,O chelate carbonyl tungsten(0) complex (1) reacts with phosphines by opening of the chelate ring to form [(CO)4(PR3)WC(OMe)C6H4OMe-o] (R = Me (5), nBu (6), Ph (7), Cy (8)). Treatment of 5 and 6 with SnX4 affords by oxidative decarbonyla
