The phosphine Ph2PCH2OH reacts with (COD)PtCl2 to form cis-PtCl2 (Ph2PCH2OH)2], the structure of which has been determined by X-ray crystallography. Similarly, the phosphines Ph2PCH2NHR (R = But, C6H4Me-4) react with (COD)PtCl2 to form cis-[PtCl2(Ph2PCH2NHR)2], although for R = C6H4Me-4 this complex is unstable and [PtCl2(Ph2PCH2)2NR}] (R = C6H4Me-4) is isolated. The complexes [PtCl2Ph2PCH2)2NR}]
膦Ph 2 PCH 2 OH与(COD)PtCl 2反应形成顺式-PtCl 2(Ph 2 PCH 2 OH)2 ],其结构已通过X射线晶体学确定。类似地,尽管对于R ,膦Ph 2 PCH 2 NHR(R = Bu t,C 6 H 4 Me-4)与(COD)PtCl 2反应形成顺式-[PtCl 2(Ph 2 PCH 2 NHR)2 ]。 = C 6 H 4在Me-4中,该络合物不稳定,并分离了[PtCl 2 (Ph 2 PCH 2)2 NR}](R = C 6 H 4 Me-4)。配合物[PtCl 2 Ph 2 PCH 2)2 NR}可以直接由(COD)PtCl 2和(Ph 2 PCH 2)2 NR制备。

periods, but show rapid proton/deuterium exchange even of the α-CH proton in deuteriomethanol and thus increased CH acidity compared with normal α-amino acids. This and the sensitivity to hydrolysis hint at an acetal-like character and partial protonation even at the phosphorus atom. Oxidation of the N-aryl derivatives 1b,c by aqueous H 2 O 2 proceeds more rapidly than hydrolysis and provides the first examples

The phosphines Ph2PCH2NHR (R = But, C6H4Me-4) react with [Mo(CO)4(norbornadiene)] or [Mo(CO)4(piperidine)2] to form cis-[Mo(CO)4(Ph2PCH2NHR)2]. The crystal structure has been determined for R = C6H4Me-4. Reaction of these complexes with aqueous formaldehyde gives the complexes [Mo(CO)4}(Ph2PCH2)2-NR}] which were also prepared independently from (Ph2PCH2)2NR.
膦Ph 2 PCH 2 NHR(R = Bu t,C 6 H 4 Me-4)与[Mo(CO)4(降冰片二烯)]或[Mo(CO)4(哌啶)2 ]反应形成顺式-[ Mo(CO)4(Ph 2 PCH 2 NHR)2 ]。对于R = C 6 H 4 Me-4,已经确定了晶体结构。这些配合物与甲醛水溶液反应生成配合物[Mo(CO)4 }(Ph 2 PCH 2)2 -NR}],它们也独立于(Ph2 PCH 2)2 NR。
