Hi,
According to your description, you want to rename file in the document library using SharePoint Client Object Model.
Here is a code snippet works well in my environment for your reference:
static void Main(string[] args)
string url = "http://sp2013sps/sites/test/";
ClientContext clientContext = new ClientContext(url);
Microsoft.SharePoint.Client.List spList = clientContext.Web.Lists.GetByTitle("Documents");
clientContext.Load(spList);
clientContext.ExecuteQuery();
if (spList != null && spList.ItemCount > 0)
Microsoft.SharePoint.Client.CamlQuery camlQuery = new CamlQuery();
camlQuery.ViewXml =@"<View> <Query> <Where><Eq><FieldRef Name='LinkFilenameNoMenu' /><Value Type='Computed'>New Microsoft Word Document.docx </Value></Eq></Where> </Query> <ViewFields><FieldRef Name='Title' /></ViewFields> </View>";
ListItemCollection listItems = spList.GetItems(camlQuery);
clientContext.Load(listItems);
clientContext.ExecuteQuery();
listItems[0]["Title"] = "word.docx";
listItems[0]["FileLeafRef"] = "word.docx";
listItems[0].Update();
clientContext.ExecuteQuery();
