A novel, green, eco-friendly and cost-effective biological route for the synthesis of palladium nanoparticles (PdNPs) from commercially available palladium chloride and easily isolable hormone Oxytocin as reducing agent is reported here. Characterization of PdNPs were done using various techniques, UV–visible spectroscopy, XRD, TEM and EDAX, characterization data confirmed the formation of Pd⁰ from Pd²⁺. The size of synthesized PdNPs were 15–20 nm. The scope of Pd nanoparticles was studied for the C–C bond formation Suzuki reaction. The catalytic activity of PdNPs was excellent in short reaction time and reaction works in green solvent water as well as catalyst can be recycled. Simple and efficient approach for total synthesis of aspongpyrazine A of the recently isolated natural substance is described.

本文报道了一种新颖的，绿色的，环保的，具有成本效益的生物路线，用于从可商购的氯化钯和易分离的激素催产素作为还原剂合成钯纳米颗粒（PdNP）。使用各种技术，紫外可见光谱，XRD，TEM和EDAX对PdNPs进行表征，表征数据证实了由Pd ²⁺形成Pd ⁰。合成的PdNP的大小为15–20 nm。研究了Pd纳米粒子的范围，用于C–C键形成Suzuki反应。PdNPs的催化活性在短的反应时间内是极好的，并且在绿色溶剂水中的反应也可以进行，并且催化剂可以循环使用。描述了一种简单有效的方法，用于合成最近分离出的天然物质阿斯吡嗪A。
