Okay, the user wants me to translate "boron compounds" into Simplified Chinese. Let me check if the original text is already in Simplified Chinese. The term "boron compounds" is in English, so I need to translate it.
First, "boron" is 硼 in Chinese. Then "compounds" would be 化合物. So putting it together, it should be 硼化合物. I need to make sure there's no existing Simplified Chinese version that's different. Since the original is English, the translation is straightforward. I'll output just the translation without any explanations as per the rules.
