Section 4 - FIRST AID MEASURES
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.

They can spread along the ground and collect in low or confined areas. Runoff from fire control or dilution water may cause pollution.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Use agent most appropriate to extinguish fire.

  作者：Jin-Long Gong、Xinxin Qi、Duo Wei、Jian-Bo Feng、Xiao-Feng Wu

  DOI：10.1039/c4ob01633e

  日期：——

  An interesting procedure for the oxidative cleavage of benzylic C–N bonds has been developed. Using TBAI as the catalyst and H2O2 as the oxidant, various benzylamines were transformed into their corresponding aromatic aldehydes in moderate to good yields. Notably, this is the first example of an oxidative cleavage of benzylic C–N bonds under metal-free conditions.
