## Abstract The reaction of the vinylidene complexes [(C~5~H~5~)(CO)(NO)W=C=C(H)R] (10a: R = __t__Bu; 10b: R = Ph) with the arsaalkene __t__BuC(O)–As=C(NMe~2~)~2~ (11) afforded the novel η^2^‐1‐arsaallene complexes [η^2^‐{__t__BuC(O)–As=C=C(H)R}W(CO)(NO)C~5~H~5~] (13: R = __t__Bu; 15: R = Ph). Simi
Synthesis of the η2-1-Phosphaallene Complexes [(η5-C5H5)(CO)(NO)W{η2-R1P=C=C(R2)H}] (R1 = tBu, Cy; R2 = Ph, H) from [(η5-C5H5)(CO)(NO)W=C=C(R2)H] (R2 = Ph, H) and Inversely Polarized Phosphaalkenes R1P=C(NMe2)2 (R1 = tBu, Cy), and Their Structure

## Abstract Reaction of [(η^5^‐C~5~H~5~)(CO)~2~M=P=C(SiMe~3~)~2~] [where M = Mo (2), W (5)] with the phosphaalkene __t__BuP=C(NMe~2~)~2~ (1a) afforded the η^3^‐1,2‐diphosphaallyl complexes [(η^5^‐C~5~H~5~)(CO)~2~M{η^3^‐__t__BuPPC(SiMe~3~)~2~}], [where M = Mo (3a); M = W (6)]. Similarly, 2 and CyP=C
Copolymerization of ethylene with 1-octadecene was studied using [g 5 :g (1, 2), Me (3), Ph (4)] as catalysts in the presence of Al(i-Bu) 3 and [Ph 3 C][B(C 6 F 5 ) 4 ]. The effect of the concentration of comonomer in the feed and Al/Ti molar ratio on the catalytic activity and molecular weight of
