  Condensation of Tp‘(CO)2M⋮CCl [1a, M = Mo; 1b, W; Tp‘ = HB(3,5-Me2HC3N2)3] with the arsaalkene Me3SiAsC(NMe2)2 afforded the novel arsaalkenyl carbyne complexes Tp‘(CO)2M⋮C−AsC(NMe2)2 (2a) (M = Mo) and 2b (M = W). Methylation of 2a and 2b occurred at the arsenic atom to give the complexes [Tp‘(CO)2M⋮CAs(Me)C(NMe2)2](SO3CF3) 3a (M = Mo) and 3b (M = W). Compounds 2a,b and 3a,b have been characterized

  Tp'（CO）2 M⋮CCl [ 1a，M = Mo; 1b，W; Tp'= HB（3,5-Me 2 HC 3 N 2）3 ]与arsalkene Me 3 SiAs C（NMe 2）2提供新颖的arsaalkenyl carbyne配合物Tp'（CO）2 M⋮C-As C（NMe 2）2（2a）（M = Mo）和2b（M = W）。2a和2b的甲基化发生在砷原子上，得到配合物[Tp'（CO）2 M⋮CAs（Me）C（NMe 2）2 ]（SO 3 CF 3）3a（M = Mo）和3b（M = W）。化合物2a，b和3a，b已通过IR，1 H和13 C NMR光谱表征。另外，已经通过单晶X射线结构分析确定了2b的分子结构。

  Reaction of [Cp(CO)(2)M=P=C(SiMe3)(2.)] (where M = Mo (3a), W (3b)] with 2 equiv of the arsaalkene PhC(O)As=C(NMe2)(2) afforded the metalloarsaalkenes Cp(CO)(2)M-As=C(Ph)-O-P-O-C(Ph)=As-C(SiMe3)(2) [where M= Mo (6a), W (6b)]. Small amounts of [eta(3):eta(3)-(Me3Si)(2)CPAs-AsPC(SiMe3)(2)}- Mo(CO)(2)Cp}(2)] (7) were formed as a minor product. Similarly, 3b and 2 equiv of 4-EtC6H4C(O)As= C(NMe2)(2) gave rise to the formation of [Cp(CO)(2)W-As=C(4-EtC6H4)-O-P-O-C(4-EtC6H4)=As- C(SiMe3)(2)] (8). However, treatment of 3a and 3b with an excess of tBuC(O)As=C(NMe2)(2) yielded cocrystals of the eta(3)-2-phospha-1,3-diarsaallyl complexes [Cp(CO)(2)Meta(3)-tBuC(O)AsPAsC(O)tBu}] [where M = Mo (13a), W (13b)] and the eta(3)-1,2,3-triarsaallyl complexes [Cp(CO)(2)Meta(3-)tBuC(O)AsAsAsC-(O)tBu}] [where M = Mo (14a), W (14b)] in varying ratios. Reaction of 3a with Me3SiAs=C(NMe2)(2) afforded the dinuclear 1,2-diphosphapropene complex [eta(2):eta(2)-(Me3Si)(2)C=P-P(H)-C(H)(SiMe3)(2)}Mo-(CO)(2)Cp}(2)] (15). The novel compounds 6a,b, 8, 13a,b, 14a,b, and 15 were characterized by means of spectroscopy (IR and H-1, C-13H-1}, P-31 NMR). Moreover the molecular structures of 7, 8, 13a, 14a, 13b, 14b, and 15 were determined by X-ray diffraction analyses.
