摘　　要：采用电喷雾离子阱质谱法（ESI-MS）对两种环钯化二茂铁亚胺-膦配合物的质谱特征进行了研究，获得了它们的结构碎片信息，对其质谱裂解途径进行了解析,结果表明：在正离子检测方式下可以得到强的准分子离子峰[M-Cl]^＋和[M-1]^＋簇，它们的（＋）ESI-MS^n（n=1～4）质谱主要产生碳．膦键断裂的碎片，同时也能观察到钯-磷键的断裂．这些特征为此类化合物及其结构类似物的结构推断提供了依据．The mass spectroscopic characteristics of two cyclopalladated ferrocenylimine-phosphine complexes have been investigated by using electrospray ionization trap mass spectrometer （ESI-MS） in a multi-stage MS full scan mode. The mass spectra were interpreted according to the fragments of these compounds and their fragmentation patterns were proposed. The results indicated that the strong [ M - Cl] ^＋ ion and [ M - I] ^＋ ion clusters were obtained in the positive mode. The positive ion produced by full scan ESI-MS^n（ n = 1 -4） of each compound gave characteristic fragment ions formed via cleavages of the C-P bond and Pd-P bond in these molecules. These characteristics can be applied further to the elucidation of fragmentation of this analogue.
